This is absolutely genius. Much respect to you. I'm sure you're well-stocked to handle this, but if you need any further resources, feel free to message me; I work with some very talented people and would love to see this do justice to the source material.
Hope you produce something spectacular!

I love Fight Club (film and novel), but hated the 2004 videogame versions, because they were nothing but a Beat'em Up with a "Fight Club" label on it.
What kind of game genre shall your game be?

It's going to be an adventure RPG, going through the plot of the film. You play as the narrator of course. You start in the apartment and there will be various doors to go through, each one leads to a different narrative strand to play through.
