When starting a new campaign are there any recommended tools / methods for shared world building between players and GM?
I’m expect that that this is a bit of a Pandora’s box for indie games, but I come at this from an OSR perspective and am just starting to dabble with indie / story games (Dungeon World, Swords w/o Master, etc).
In the past my world building is more the result of emergent play, but now interested in establishing a collaborative foundation.
Finally I’ll say I’m not looking for something too complex or lengthy, rather something that can be run as part of session 0 in a hour or two.
