Modern Prometheus is a beautifully laid out text, with evocative prompts and lovely minimalist artwork. I feel like it mostly uses the system well to create the specific experience it is trying to achieve, with only one of the games that felt like it was there more as 'classic firebrands game' rather than because it necessarily fit the narrative. The decision to make the characters have specific minigames associated with them is also a really interesting design choice i haven't seen before and enjoyed. If you are looking for a game that takes you through pretty precise story beats of the Frankenstein novel, this is definitely one to give a go.
Unfortunately based on the early intro text, we thought the game was more 'frankenstein inspired' with room to generate your own narrative on the themes, since a lot of firebrands games are more about the setting and vibes than a specific outcome; and consequently we deviated from the expected plot beats early on, found the games a struggle to fit with the characters we designed and had to retool several of them. I think if we had known the more specific expectations of the game experience upfront in the preamble before getting to the minigames (a la something like Our Travelling Home), I would have had a very different time with the game and if I were to play it again, I would definitely keep that in mind.
