Portal 2

[LordSappington]

Co-op is the best I've ever seen in a game, simply because there is absolutely no room to be a dick. If you want to get anything done, you better be damn sure you're helping your partner and being at least friendly to him/her, or you'll either get dumped or repeatedly killed. I've only gotten paired with one asshole, and I just kept dumping him in the water and hitting him with cubes while he was mid-air. All the other partners I got paired with were total bros.

I finally finished single-player last night and can now look at threads about Portal 2. Absolutely fantastic game!
