Well, rp as in {rp} - the clan. There have been quite a few rp games with innovative/crazy template ideas and often these games need 'special rules' to work. You obviously can't enforce rules that lie outside of what WL's engine deals with, so instead you have to rely on the goodwill of everyone involved. You need trustworthy people to make it work and have fun. That's one reason why rp is invite-only. Anyway, every now and then Fizzer gets invited or takes an interest in a game like that. He doesn't type a lot in public chat though.
Here's an example:

Actually I'm just too lazy right now to search through my games for a really crazy one. It was either Discord or General Mac who originally came up with the SOI idea by the way (I hope I'm right).
