Tetris Party is fun, but there's no option for non-competitive Tetris--that is, Tetris where you doing well doesn't fuck over the other person. It used to be the norm I think (back in the arcade) where one person would finish a level and the other person would have to catch up.

There are tons of other little games in there, but they're mostly gimmicks. Co-op Tetris is a mess and is usually no fun. The other games are interesting but ultimately boring.

World of Goo is co-op, right? Try that, I guess?
