I’m working on a PbtA game where a core part of the tone/genre revolves around characters solving mysteries.
Now, in your standard D&D and whatnot, the theoretical approach is that the GM has planned something out beforehand and the players have to work to figure out what it is. I don’t want to do that. I want this game to be more collaborative and emergent, with the GM and the players working together to create the story.
But how can I design for that and also design for satisfying mystery arcs, with clues leading up to a twist or revelation that makes sense in the game world? What tools can I give players and the GM to make that happen? And are there any systems out there that do this well that I should look at?
