I'm making a github organization that uses GitConsensus to manage a collaborative markdown worldbuilding wiki. Basically, you'd vote on pull requests using thumbs up and down emojis.
I don't want this to be a thing where I point at an empty text document and say "worldbuild." What's some work I could do beforehand that could get people interested in contributing?
I don'tthink you should limit it to one specific TTRPG System. I mean, what does gameplay mechanics have to do with a setting. So make it system agnostic by introducing common assumptions and build upon them. Introduce your own pantheon, races, magic and powers etc.
This would make the worldbuilding appeal to way more people.
I think we'd start with a medieval fantasy world. Its purpose would be to provide writers and RPG playerd with an in depth setting that isnt copyrighted. I want it to be a folk storytelling thing where all ideas are free to use and remix.
