Not sure if it's the right title for the thread as this is something I haven't been able to find more information about. Perhaps it's just that I haven't found yet the proper keywords to google it. I´m pretty sure lots of different games and GMs have been using different tools for this since ages ago, so it's nothing new, it should be out there somewhere.
What I'm looking for is any tool, prop, procedure, technique, loaded questions, etc to help players express their expectations towards the game and the content in the fiction. Like when you brainstorm a setting, region, organization or group of NPCs with the players.
My goal is to design a game that can help the GM produce quality content with the player's help so it mets their expectations, instead of giving the GM a load of work along with the responsability of meeting such expectations. It should be able to bypass blank-page syndrome and czege's principle issues. It should produce enough coherent content to spark the player's and GM imagination while avoiding derrailing, gonzo or murderhobo gameplay. And it should be quick. As I say, nothing new, plenty of games/GMs already do this but as most I've found doesn't meet my own particular expectations I went and tried to make my own by hacking too much of them to leave anything recognizable.
Anyway, part of the problem that I can't find too much of what I'm looking for is that I'm going for a somewhat trad gameplay feeling: the GM frames the challenges for the players, they control their characters, conflict resolution is triggered by whatever the GM deems as a challenge. But most of these type of games GMing philosophy goes around having the GM prep the setting and adventure or use pre-made ones, so I didn't had much luck researching there, with a few exceptions.
Indie games were another story. It took me a long time but now I have a close idea of how to approach the design. So far I solved the quick worldbuilding part (though I still think I can make some shortcuts there) in a way that it ignites the spark for adventure creation. Here I want to help players create a premise for the adventure that gets them invested (I can even make this in play). Adventure creation still needs some work though. The challenges still need work too. In the next post I'll list some of the tools I'm using to give you a better idea of what I'm looking for.
