Sir Paul McCartney had a video game. It is pretty awful, but it's also fascinating.
I really like weird games. Cubivore. Katamari Damacy. Gitaroo Man. As a gamer, some of my favorite experiences are the weirdest ones out there. When I go to the store or preorder games, I preferentially choose the weird ones; the runts of the litter, the ones that people don't play that often.
