Okay, thoughts on a system of world building. Fun, or dumpster fire?
1. Each player comes up with three somethings for the world. Can be a few words, or up to a paragraph. Write each on a seperate piece of paper.
2. We shuffle papers. You take the 3 you now have and modify/change it as you see fit.
3. Each person vetos one idea of the 3 they have. The remaining two ideas are read out loud.
4. Players vote the ideas down to half (so if there's 5 players + 1 GM, now there's 6 ideas floating around)
