I've played...

Dungeons and Dragons
Tunnels and Trolls
Mustangs and Messerschmidts
Animals and Assholes... (my favorite... at any gamers convention, you pick up a typical unwashed teenaged gamer by the collar and ask "I'm and Animal. What are you?")

Right now I'm refining a personal version of Dungeons and Dominants. Gives a whole new meaning to the term Dungeon Master.
