Here's some more:

The Skeletons - From the folks behind Fiasco. Another GM-less game. It's about playing some skeletal guardians of an ancient tomb who defend it from adventures and other intruders. It's a lot more meditative and quiet then the description, but you also get to draw some skele-friends. I really want to do a hack/expansion for it, since the game-as-is is a bit content-lite for multiple play-throughs.

Goblin Quest - This is a game about goblins going on a quest of the utmost importance. It's silly and has a lot of cartoon violence. It also comes with a lot designer made hacks that I've never played but always wanted to.
