RPG safety tools: A set of categories I've used for setup discussion that worked well.
- Hard Omissions are things that are unwelcome, regardless of handling: Just don't.
- Soft Omissions are things that can only be played on after a check-in.
- Soft Inclusions are things that are assumed to be cool to play to and on, but players can opt out of.
- Hard Inclusions are things that are built into the core premise or mechanics of game itself at some level, and which can't really be avoided.
