I know this may not be the best place to ask this, since it's for a game, but the game is very story driven, so I thought it would be reasonable to ask this on the writers stack exchange.
The story is far from complete - I don't usually write stories for my games, so I'm unsure of how to start. I already have TONS of notes... for the plot, scenes, characters, setting, dialog snippets, all sorts of things, but I'm having trouble bringing it all together to plan for the game it was made for.
How should I structure the story? Would it make sense to write it out like a book, so everybody on the team knows exactly what the story is about? Or should it be more concise and to the point? What would help best when we start working on the actual game?
About the game itself: It's an RPG Maker type of video game inspired by games from the Corpse Party series, which also first started from an RPG Maker game. It even has a similair setup, with a group of people trapped in a haunted place, but with a twist on how time works in that haunted place, leading to interesting situations.
