The Order of the Stick board game?

Personally, I hated it with a flaming passion. Caveat: I don't like cooperative-competitive games, games where you have to cooperate with others to succeed and yet must also screw each other over to win. I nearly walked out on an Order of the Stick game because no one would support me in battle, and so I was just screwed.

I know that reaction isn't good gamesmanship -- but I just won't play that game anymore.
