Description

  The present invention sets the clock date and time stored in the game device in a game in which the date and time in the game progresses in conjunction with the actual date and time by using a calendar function and a clock function built in the game device. The present invention relates to a game device, a game control method, and a program for realizing these on a computer, which are suitable for preventing unauthorized alteration of the clock time that deviates from the actual date and time.

  A game is known in which the date and time in the game progresses in conjunction with the actual date and time (real time) by using a calendar function and a clock function built in the game device. However, in such a game, in order to generate an in-game event (for example, a holiday, Christmas, etc.) that occurs in conjunction with real time, the player intentionally changes the date and time in the game, and the event is arbitrarily set. If generated, game performance may be impaired. Therefore, Patent Document 1 performs a process of clearing (initializing) the progress of the game when the player changes the date and time.

Japanese Patent No. 3683632

  However, if the in-game time is cleared due to an error in the operation of the clock in the game device or a change due to a secular change, the player is discouraged from trying to advance the game. On the other hand, there is a need for a technique for preventing unauthorized alteration of clock time as much as possible.

  The present invention has been made in view of the above problems, and in a game in which the date and time in the game advances in conjunction with the actual date and time by utilizing the calendar function and the clock function built in the game device, A game device, a game control method, and a program for realizing these on a computer, which are suitable for preventing unauthorized alteration of the clock time that shifts the clock date and time setting stored in the game device from the actual date and time The purpose is to provide.

  In order to achieve the above object, a game device according to a first aspect of the present invention includes a timekeeping unit, a storage unit, and a warning unit.

  The timekeeping section keeps time and date. The timekeeping unit includes, for example, an RTC (Real Time Clock), and functions as a calendar or a clock by measuring the date and time (including year / month / day / hour / minute / second and day of the week).

  The timekeeping unit can also acquire a standard time by connecting to a computer communication network such as the Internet, and time the date based on the standard time.

  When an event occurs, the storage unit stores the generated information indicating that the event has occurred in association with the time and date. When an event occurs when the date and time in the game reaches a predetermined date and time, generated information indicating that the event has already occurred and occurrence date and time information when the event occurs are stored in association with each other. The

  Here, the event is an arbitrary event that occurs in the game, and means, for example, that the player has acquired a predetermined item, cleared a predetermined stage, or defeated a predetermined enemy character.

  The warning unit compares the stored date and time with the measured date and time, and warns when the former is the future of the latter. The warning unit compares the event occurrence date / time information when the event stored in the storage unit occurs with the actual date / time information timed by the timing unit, and the event occurrence date / time information is advanced from the actual date / time information. It is judged whether it is in the future (the future). In the future, the warning unit issues a warning to the player.

  In the game, since the game date and time advances in conjunction with the actual date and time, if an event has already occurred, the event occurrence date and time information stored is delayed from the actual date and time information (in the past) There should be. However, when the event occurrence date / time information is ahead of the actual date / time information (in the future), it is determined that the unauthorized clock time has been tampered with, so a warning is given to the player. Done.

  As a result, it is possible to prevent unauthorized alteration of the clock time that shifts the stored clock date and time from the actual date and time.

  In addition, the game device compares the stored date and time with the measured date and time, and when the former is the future of the latter, the occurrence is stored in association with the date and time of the future from the storage unit. An erasing unit for erasing the completed information may be further provided.

  The erasure unit compares the event occurrence date / time information when the event stored in the storage unit occurs with the actual date / time information timed by the timing unit, and the event occurrence date / time information is advanced from the actual date / time information. It is judged whether it is in the future (the future). If it is in the future, the erasure unit erases the generated information and the already generated event.

  For example, when there is a predetermined item that can be acquired only at Christmas time, it is assumed that the player acquires the item by performing falsification that advances the clock time to Christmas time. Thereafter, when the player returns to the clock time before falsification, the item is acquired even though the date and time in the game is before the Christmas time. In this case, assuming that the item has been acquired by an unauthorized method, the item acquired by the player is deleted, and the state before the alteration is performed is returned.

  As a result, when the player falsifies the illegal clock time that shifts the date and time, since the already generated event is deleted, the player's will to falsify the illegal clock time can be discouraged.

  It is also possible to reduce the probability that an event for the deleted generated information will occur. For example, if there is an item that can be acquired with a probability of 50% at Christmas time, the probability is reduced to 30% or 10% if an unauthorized alteration of the clock time is performed.

  As a result, when the player falsifies an illegal clock time that shifts the date and time, a disadvantageous process is performed for the player, so that the player's will to falsify the illegal clock time can be distracted.

  In order to achieve the above object, a game control method according to another aspect of the present invention is assumed to have a timing unit, a storage unit, and a warning unit, and to proceed in conjunction with the actual date and time. A game control method that is executed by a game device that realizes a game in which an event occurs in accordance with progress, and includes a time measuring step, a storing step, and a warning step.

  In the timing process, the timing unit counts the date and time.

  In the storing step, when an event occurs, the storage unit stores generated information indicating that the event has occurred in association with the time and date.

  In the warning process, the warning unit compares the stored date and time with the measured date and time, and warns when the former is the future of the latter.

  As a result, it is possible to prevent unauthorized alteration of the clock time that shifts the stored clock date and time from the actual date and time.

  A program according to another aspect of the present invention is configured to cause a computer to function as the game device described above and to cause the computer to execute the game control method described above.

  The program of the present invention can be recorded on a computer-readable information recording medium such as a compact disk, flexible disk, hard disk, magneto-optical disk, digital video disk, magnetic tape, and semiconductor memory. The above program can be distributed and sold via a computer communication network independently of the computer on which the program is executed. The information recording medium can be distributed and sold independently of the computer.

  According to the present invention, it is possible to prevent unauthorized alteration of the clock time that shifts the stored clock date and time from the actual date and time. Further, it is possible to discourage the player's will to alter the illegal clock time.

  Note that a DVD-ROM storing a game program and data is loaded into the DVD-ROM drive 107, and the information processing apparatus 100 is turned on to execute the program. Realized.

  The CPU 101 controls the overall operation of the information processing apparatus 100 and is connected to each component to exchange control signals and data.

  The ROM 102 records an IPL (Initial Program Loader) that is executed immediately after the power is turned on, and the CPU 101 reads the program recorded on the DVD-ROM into the RAM 103 and executes it. The ROM 102 stores an operating system program and various data necessary for operation control of the entire information processing apparatus 100, and the CPU 101 reads and executes these programs.

The RAM 103 is for temporarily storing data and programs, and holds programs and data read from the DVD-ROM and other data necessary for the progress of the game.
In addition, the CPU 101 provides a variable area in the RAM 103, performs processing by directly operating the ALU on the value stored in the variable, and temporarily stores the value stored in the RAM 103 in the register. Performs an operation on the register and writes the result back to the memory.

  The controller 105 connected via the interface 104 receives an operation input performed when the user executes the game. For example, the controller 105 includes an A button, a B button, an X button, a Y button, direction buttons (direction keys) indicating four directions, and the like. When these buttons are pressed by the user, an operation input corresponding to the pressed button is accepted.

  In the external memory 106 detachably connected via the interface 104, data indicating the progress of the game, communication log (record) data, and the like are stored in a rewritable manner. The user can record these data in the external memory 106 as appropriate by inputting an instruction via the controller 105.

  A DVD-ROM mounted on the DVD-ROM drive 107 stores a program for realizing the game and image data and sound data associated with the game. Under the control of the CPU 101, the DVD-ROM drive 107 performs a reading process on the DVD-ROM loaded therein, reads out necessary programs and data, and these are temporarily stored in the RAM 103 or the like.

  The image processing unit 108 processes the data read from the DVD-ROM by the CPU 101 or an image arithmetic processor (not shown) included in the image processing unit 108, and then processes the processed data on a frame memory ( (Not shown). The image information recorded in the frame memory is converted into a video signal at a predetermined synchronization timing and output to a monitor (not shown) connected to the image processing unit 108. Thereby, various image displays are possible.

The image calculation processor can execute a two-dimensional image overlay calculation, a transmission calculation such as α blending, and various saturation calculations at high speed.
In addition, the polygon information arranged in the virtual three-dimensional space and added with various kinds of texture information is rendered by the Z buffer method, and a rendered image is obtained by overlooking the polygon arranged in the virtual three-dimensional space from a predetermined viewpoint position. High speed execution of the obtained operation is also possible.

  Further, the CPU 101 and the image arithmetic processor cooperate to draw a character string as a two-dimensional image in the frame memory or draw it on the surface of each polygon according to the font information that defines the character shape. Is possible. The font information is recorded in the ROM 102, but it is also possible to use dedicated font information recorded in the DVD-ROM.

  The audio processing unit 109 converts audio data read from the DVD-ROM into an analog audio signal, and outputs the analog audio signal from a speaker (not shown) connected thereto. Further, under the control of the CPU 101, sound effects and music data to be generated during the progress of the game are generated, and sound corresponding to this is output from the speaker. The sound processing unit 109 converts, for example, the sound of music reproduced as BGM or karaoke, or the sound effect reproduced in accordance with the user's button operation.

  The NIC 110 is used to connect the information processing apparatus 100 to a computer communication network (not shown) such as the Internet, and is based on the 10BASE-T / 100BASE-T standard used when configuring a LAN (Local Area Network). To connect to the Internet using an analog modem, ISDN (Integrated Services Digital Network) modem, ADSL (Asymmetric Digital Subscriber Line) modem, cable television line A cable modem or the like and an interface (not shown) that mediates between these and the CPU 101 are configured.

  The RTC 111 is a time measuring device including a crystal resonator and an oscillation circuit. The RTC 111 is supplied with power from the built-in battery and continues to operate even when the information processing apparatus 100 is powered off.

In addition, the information processing apparatus 100 uses a large-capacity external storage device such as a hard disk so as to perform the same function as the ROM 102, the RAM 103, the external memory 106, the DVD-ROM attached to the DVD-ROM drive 107, and the like. You may comprise.
In addition, it is possible to adopt a form in which an input / output device such as a keyboard for receiving a character string editing input from a user and a mouse for receiving various position designations and selection inputs is connected.

  Further, instead of the information processing apparatus 100 of the present embodiment, a general computer (general-purpose personal computer or the like) can also be used as the game apparatus according to the present invention. For example, a general computer includes an CPU, a RAM, a ROM, a DVD-ROM drive, and an NIC, as in the information processing apparatus 100, and an image processing unit having a simpler function than the information processing apparatus 100. In addition to having a hard disk as an external storage device, a flexible disk, a magneto-optical disk, a magnetic tape, and the like can be used. In addition, a keyboard, a mouse or the like is used as an input device instead of a controller. And after installing a game program, when the program is run, it can be functioned as a game device.

  Hereinafter, unless otherwise noted, the game apparatus described later will be described by the information processing apparatus 100 shown in FIG. The game apparatus can be appropriately replaced with general computer elements as necessary, and these embodiments are also included in the scope of the present invention.

(Game description)
FIG. 2 is a diagram for explaining the progress of the game in the game realized by the game device according to the present embodiment. Hereinafter, the game will be described with reference to FIG.

  The game device includes an RTC (Real Time Clock), and when the actual date and time (including year and day of the week) progresses, the date and time in the game also progresses in conjunction with each other. For example, if the actual date / time is 12:00 on January 1st, the date / time in the game will also be 12:00 on January 1st, and if the actual date / time progresses 1 day, the date / time in the game will also progress 1 day. To do.

  It should be noted that the date and time in the game that proceeds in conjunction with the actual date and time can be advanced at an arbitrary speed. For example, when the actual date and time has passed 24 hours, the date and time in the game can be passed 12 hours or 48 hours. In other words, the date and time in the game can be advanced at a speed different from the speed at which the actual date and time progress, and the actual date and time do not need to be exactly the same.

  In the game, a predetermined event linked to the actual date and time occurs. For example, on December 25, processing such as displaying an image for Christmas is performed. Further, every time the actual date and time advances, a process for generating an event such as the appearance of a new item is performed. The predetermined event is arbitrary, for example, the appearance of a new item, the appearance of a character, or the appearance of a map.

  For example, when the date and time in the game is January 1st, an event 1 in which the item 1 appears is generated, and when the date and time in the game is January 2nd, an event 2 in which the item 2 appears is generated. Then. Since the date and time in the game progresses in conjunction with the actual date and time, events 1 and 2 do not occur unless the actual date and time progress, and the player cannot acquire both items 1 and 2. Therefore, the player can enjoy a predetermined event that occurs in conjunction with the actual date and time by playing the game according to the progress of the actual date and time.

(Configuration of game device)
A schematic configuration of game device 200 according to the present embodiment will be described with reference to FIG. The game device 200 includes a timing unit 201, a storage unit 202, a progress unit 203, a warning unit 204, an erasing unit 205, and a changing unit 206. Hereinafter, each component of the game apparatus 200 will be described.

  In addition, although the function of each part is mutually linked | related, the acceptance / rejection of each part can be changed suitably according to a use. In addition, the game apparatus 200 appropriately includes a reception unit that receives an operation input performed by the player.

  The time measuring unit 201 measures (counts) the current date and time (including year / month / day / hour / minute / second and day of the week). The timekeeping unit 201 functions as a calendar and a clock by measuring the current date and time. The timekeeping unit 201 causes the storage unit 202, which will be described later, to store the current date and time that is timed regularly (every fixed time, when an event occurs in the game).

  In addition, the timer unit 201 can acquire a standard time by connecting to a computer communication network such as the Internet through the NIC 110, and can count the date and time based on the standard time.

  The CPU 101, the ROM 102, the RTC 111, and the like operate in cooperation to function as the time measuring unit 201.

  The storage unit 202 stores the current date and time measured by the time measuring unit 201 and the date and time in the game linked to the current date and time. In addition, when an event occurs, the storage unit 202 stores generated information indicating that the event has occurred and an occurrence date and time when the event has occurred in association with each other.

  FIG. 4 is a configuration example of event occurrence information stored in the storage unit 202. In the storage unit 202, for each event type, generated information indicating whether or not the event has already occurred, date and time information (recording date and time) when the event has already occurred, event Are stored in association with each other, information indicating the contents of the event, event occurrence conditions, and the like.

  In addition, the storage unit 202 stores the occurrence probability of an event that is changed by the changing unit 206 described later. FIG. 5 is a diagram illustrating a variation example of the occurrence probability of an event stored in the storage unit 202. As shown in the figure, the storage unit 202 stores, for each event type, information indicating the degree of profit of the event, event occurrence probability information before change, and event occurrence probability information after change.

  Here, the profit level shown in the figure is an index indicating whether it is beneficial or disadvantageous for the player to advance the game. In other words, a good event profit level means an event that is beneficial to the player, such as an event in which an expensive item appears or a powerful weapon appears. Further, the event having a low profit level means an event that is disadvantageous to the player, for example, an event in which many enemy characters appear or the degree of difficulty increases.

  The CPU 101, the RAM 103, the external memory 106, and the like operate in cooperation to function as the storage unit 202.

  The progression unit 203 advances the date and time in the game in conjunction with the actual date and time counted by the timing unit 201. In addition, the progression unit 203 generates a predetermined event in conjunction with the actual date and time to advance the game.

  The progression unit 203 accepts an input operation from the player that is input through the controller 105, and advances the game.

  The CPU 101, the RAM 103, the controller 105, and the like work together to function as the progression unit 203.

  The warning unit 204 compares the date and time stored in the storage unit 202 with the date and time measured by the timing unit 201, and warns when the former is the future of the latter. In the game, since the game date and time advances in conjunction with the actual date and time, if an event has already occurred, the event occurrence date and time information stored is delayed from the actual date and time information (in the past) There should be. However, when the event occurrence date / time information is ahead of the actual date / time information (in the future), it is determined that the unauthorized clock time has been tampered with. Warn against.

  FIG. 6 is a diagram for explaining alteration of the clock date and time. First, it is assumed that the player starts the game from “date 2”. After the game starts, the actual date and time progresses, and an event occurs at “date and time 3”. When an event occurs, the fact that the event has already occurred and that the occurrence date and time of the event is “date and time 3” are stored in association with each other. After the event, the game ends at “date 4”. Thereafter, when the player changes the actual date and time counted by the game device 200 to “date and time 1” that is a time before “date and time 4”, the date and time in the game proceeds in conjunction with the actual date and time. The date and time in the game also changes from “date and time 4” to “date and time 1”.

  In this case, although the date and time in the current game is “date and time 1”, an event that should occur at “date and time 3” has already been stored. That is, there is a trap that an event occurring at “date 3”, which is in the future from “date 1”, has already occurred. For this reason, when the occurrence date and time of the stored event is ahead of the time and date to be measured (in the future), it is determined that the unauthorized clock date and time has been tampered with.

  As described above, when it is determined that the unauthorized clock date / time has been tampered with, the warning unit 204 issues a warning to the player.

  Note that a method of giving a warning to the player is arbitrary, and for example, a display or a sound for prompting the player not to falsify can be output through a monitor or a speaker.

  The CPU 101, the image processing unit 108, the sound processing unit 109, and the like operate in cooperation to function as the warning unit 204.

  The erasure unit 205 compares the date and time stored in the storage unit 202 with the date and time measured by the timing unit 201. If the former is the future of the latter, the deletion unit 205 associates the date and time with the future from the storage unit 202. Delete information that has already been stored and events that have occurred. When the generated information and the event are deleted by the deleting unit 205, for example, the item acquired by the player, the flag information indicating the progress state of the game, and the like are deleted. As a result, the state before tampering is restored.

  FIG. 7 is a diagram for explaining the event erasure performed by the erasure unit 205. First, it is assumed that an event has already occurred at the time “date and time 3”, and the date and time of occurrence (recording date and time) of the event is stored as “date and time 3”. The game is started from the time “date 1” by the player performing the alteration to return the actual date and time counted by the game apparatus 200 to the date before “date 3”. Then, at the time of “date and time 2” which is an arbitrary date and time, the date and time in the game (here “date and time 2”) and the event occurrence date and time (here “date and time 3”) are compared. Then, although the date and time in the current game is “date and time 2”, an event has already occurred at the time and date “date and time 3”, which is the future of “date and time 2”. It will be erased.

  The CPU 101, the RAM 103, and the like operate in cooperation to function as the erasing unit 205.

  The changing unit 206 changes the event occurrence probability for generating a predetermined event. For example, as shown in FIG. 5, the changing unit 206 changes the probability that the event 1 occurs from 100% to 80%, or changes the probability that the event 3 occurs from 50% to 70%. Or By varying the event occurrence probability, it is possible to reduce the probability of appearing an item that is beneficial to the player, and to increase the probability of appearing an enemy character that is disadvantageous.

  The CPU 101, the RAM 103, and the like operate in cooperation to function as the changing unit 206.

(Memory processing operation)
Next, the operation of the storage process executed by the game apparatus 200 will be described with reference to the flowchart of FIG. This process is a process for associating and storing the occurrence date and time information when an event has occurred and the occurrence information indicating that the event has already occurred.

First, the CPU 101 acquires the current date and time counted by the RTC 111 (step S101). The current date and time counted by the game apparatus 200 can be set by the player himself / herself through the controller 105, or the date and time acquired by connecting to a computer communication network such as the Internet through the NIC 110 can be set.
The CPU 101 and the RAM 103 operate in cooperation to function as the timer unit 201.

The CPU 101 advances the date and time in the game in conjunction with the current date and time (step S102). The game date and time need only be linked to the current date and time, and the actual date and time in the game do not need to match completely. For example, when the actual date / time progresses for one hour, the date / time in the game progresses for 24 hours, so that it can be advanced at different speeds. Further, when the current date / time advances for one hour, the date / time in the game also advances for one hour.
The CPU 101 and the RAM 103 operate in cooperation to function as the progression unit 203.

  Next, the CPU 101 determines whether or not a condition for generating a predetermined event is satisfied (step S103). For example, the condition may be arbitrarily selected such that the date and time in the game is a predetermined date and time, a predetermined input condition by an input operation from the player is satisfied, a predetermined input operation is performed at a predetermined date and time, etc. is there.

  For example, as shown in FIG. 2, when the date and time in the game is 12:00 on January 1, the event 1 occurs, and when the game progresses and the event 2 occurs at 12:00 on January 2, The occurrence condition of event 1 is that the date and time in the game has passed 12:00 on January 1, and the occurrence condition of event 2 is that 12:00 on January 2 has passed.

  When the condition for generating an event is satisfied (step S103; Yes), the CPU 101 generates an event that satisfies the condition (step S104). The content of the event to be generated is arbitrary. For example, it is performed in the game such as changing the background displayed on the monitor, displaying a predetermined comment, causing a predetermined item to appear, or causing a predetermined character to appear. All phenomena are included.

  On the other hand, when the condition for generating an event is not satisfied (step S103; No), the CPU 101 continues the progress of the date and time in the game (step S102).

Next, the CPU 101 stores the occurrence date / time information that generated the event and the generated information indicating that the event has already occurred in association with each other (step S105). As shown in FIG. 4, for each event, generated information indicating whether or not the event has already occurred, and if it has already occurred, the date and time when the event occurred is stored in association with each other.
The CPU 101 and the RAM 103 operate in cooperation to function as the storage unit 202.

  Through the above processing, the occurrence date and time information when the event has occurred and the occurrence information indicating that the event has already occurred are stored in association with each other.

(Warning processing operation)
Next, an operation of warning processing executed by the game apparatus 200 will be described with reference to a flowchart of FIG. This process is performed at any time, such as when the game apparatus 200 is activated, at the start of the game, at regular time intervals during the game, or at the end of the game according to the progress of the game.

  First, the CPU 101 acquires the date and time in the game (step S201).

  Next, the CPU 101 acquires event occurrence information shown in FIG. 4 and occurrence date and time information corresponding to the information (step S202).

  Next, the CPU 101 compares the occurrence date and time of the event with the acquired date and time in the game, and whether or not the event occurrence date and time is ahead of the date and time in the game (in the future). Is determined (step S203).

  The alteration of the clock date will be described with reference to FIG. First, it is assumed that the player starts the game from “date 2”. After the game starts, the actual date and time progresses, and an event occurs at “date and time 3”. When an event occurs, the fact that the event has already occurred and that the occurrence date and time of the event is “date and time 3” are stored in association with each other. After the event, the game ends at “date 4”. Thereafter, when the player changes the actual date and time counted by the game device 200 to “date and time 1” that is a time before “date and time 4”, the date and time in the game proceeds in conjunction with the actual date and time. The date and time in the game also changes from “date and time 4” to “date and time 1”.

  In this case, although the date and time in the current game is “date and time 1”, an event that should occur at “date and time 3” has already been stored. That is, there is a trap that an event occurring at “date 3”, which is in the future from “date 1”, has already occurred. For this reason, when the occurrence date and time of the stored event is ahead of the time and date to be measured (in the future), it is determined that the unauthorized clock date and time has been tampered with.

When the event occurrence date / time is later than the date / time in the game (step S203; Yes), the CPU 101 issues a warning to the player (step S204). A method for giving a warning to the player is arbitrary, and for example, a display or a sound for prompting the player not to falsify is output through a monitor or a speaker.
The CPU 101, the image processing unit 108, the sound processing unit 109, and the like operate in cooperation to function as the warning unit 204.

  On the other hand, when the event occurrence date and time is not in the future than the date and time in the game (step S203; No), the CPU 101 proceeds from the present process to the storage process to advance the game.

Next, the CPU 101 deletes the event determined that the event occurrence date / time is later than the date / time in the game (step S205). Here, erasing an event means returning the content of the game to the state before tampering. For example, erasing items illegally acquired by the player, erasing flag information indicating the progress of the game, To return the progress of the.
The CPU 101, the RAM 103, and the like operate in cooperation to function as the erasing unit 205.

  The event deletion will be described with reference to FIG. First, it is assumed that an event has already occurred at the time “date and time 3”, and the date and time of occurrence (recording date and time) of the event is stored as “date and time 3”. The game is started from the time “date 1” by the player performing the alteration to return the actual date and time counted by the game apparatus 200 to the date before “date 3”. Then, at the time of “date and time 2” which is an arbitrary date and time, the date and time in the game (here “date and time 2”) and the event occurrence date and time (here “date and time 3”) are compared. Then, although the date and time in the current game is “date and time 2”, an event has already occurred at the time and date “date and time 3”, which is the future of “date and time 2”. It will be erased.

  If it is determined that the event occurrence date / time is later than the date / time in the game, that is, if it is determined that the unauthorized clock time has been tampered with, the determination is not more than a predetermined number of times (for example, once). In such a case, it is possible to only warn the player and not delete the event. As a result, even if the date and time in the game is changed due to an unexpected accident such as battery exhaustion, the event is not erased. If the warning process is performed again within a predetermined time (for example, 24 hours) from the warning, the event can be erased as an unauthorized clock time tampering.

Further, the CPU 101 can not only delete the event that has already occurred, but also change the probability of the event to be generated in the future.
The CPU 101, the RAM 103, and the like operate in cooperation to function as the changing unit 206.

  Before changing the event occurrence probability, the CPU 101 first determines the profit level of the deleted event (step S206).

  When the profit degree of the deleted event is good (step S206; good), the CPU 101 lowers the probability of occurrence of the event (step S207). Then, the CPU 101 shifts from the main process to the storage process and advances the game.

  As shown in FIG. 5, when event 1 is a good event for the player, the occurrence probability of event 1 is lowered. Specifically, an item that appears with a probability of 100% at a predetermined date and time is reduced to an appearance rate of 80%. Thereby, since the probability that the event 1 which is a good event will occur is lower than before the unauthorized tampering, the player will play the game under unfavorable conditions when proceeding with the game in the future.

  In addition, in the case of a very good event such as event 2, the probability that event 2 will occur can be greatly reduced compared to other good events.

  On the other hand, when the profit level of the deleted event is bad (step S206; bad), the CPU 101 increases the probability of occurrence of the event (step S208). Then, the CPU 101 shifts from the main process to the storage process and advances the game.

  As shown in FIG. 5, when the event 3 is a bad event for the player, the probability of the event 3 occurring is increased.

  As the probability of a good event occurring decreases and the probability of a bad event occurring increases, the player must advance the game under adverse conditions. As a result, the player's will to try to tamper with the incorrect clock time can be discouraged.

  Further, the CPU 101 can change not only the event determined in step S203 and deleted in step S205 but also the probability of occurrence of other events. For example, if it is determined in step S203 that the occurrence date and time of event 1 is later than the date and time in the game, not only the occurrence probability of event 1 but also the occurrence probability of event 2 or event 3 is changed. You can also.

  Further, the probability of occurrence can be changed according to the number of warnings. For example, as the number of warnings increases once, twice, three times,..., The event occurrence probability is set to 100%, 90%, 80%,. It can also be varied as 50%. The rate of change of the occurrence probability to be changed according to the increase in the number of warnings is arbitrary.

  Further, before the number of warnings reaches a predetermined number (for example, 3 times), the game can be advanced without deleting the event, and the event can be deleted when the predetermined number of times is reached.

In addition, when it is determined that there is no warning for a certain time or more, that is, that unauthorized tampering has not been performed, the event occurrence probability can be restored.
In addition, the occurrence probability of an event that is indispensable for the progress of the game can be kept unchanged.

  With the above processing, it is possible to prevent an unauthorized alteration of the clock time that shifts the setting of the clock date and time stored in the game device from the actual date and time. Further, it is possible to discourage the player's will to alter the illegal clock time.

  As described above, according to the present invention, in the game in which the date and time in the game advances in conjunction with the actual date and time by using the calendar function and the clock function built in the game device, It is possible to provide a game apparatus and the like suitable for preventing unauthorized alteration of the clock time that shifts the stored clock date and time from the actual date and time.
