Yeah! it is really funny, to write a story live with the other users.
On threads @magnacarta has "The GHAWG Diaries" which is a very different version, individual, but kinda on the same idea of creating a story step by step.
It can be done by everyone just adding to the story or everyone having a character haha. As an event (even on a threadcast) this can be soooo fun! haha.
You know which kind of users could be a target for this? anime fans. pretty sure 80% have role-played
haha absolutely! We used to do events in the r/worldbuilding discord now and then were there was a general 'banquet' style scene, and any user could pull in a character from a story/world/setting they've built and RP as them in it. I'm no longer part of that team/community, but it was fun!
