FIST is a great game. Somehow fits into every setting you want it to. Enough traits and roles to make every character unique (although dominatrixes keep turning up in my games). Certainly as a player turned referee it is one of my favourite games to organise a session of. The players keep making it incredibly fun. You can make characters such as gandalf or even the human centipede. Truly a masterpiece which I am trying to get as many people to try as possible!
