The Syndicate

RYM had a game somewhat like this a couple years ago based on a Game of Thrones theme. It wasn't an open setup, so when things started it wasn't clear how it was put together -- but everyone knew by Day 2. There were no townies, everyone was on a mafia team (I think there were five of them). There were two rogues based on the Baelish and Varys characters who manipulated things with PM/BTSC dealings, and each team had statistical ratings in various categories that somehow played into who died each night when all of them sent kills. It was weird, not really "Mafia", but still something interesting.
