> I'm not being judged on how well I do, or even that I solved the problem at all, I know I can put down the game whenever and no one cares. This is why I don't think gamifying work is too useful in the long run, because deep down we know we're expected to solve those problems and get results.

Well in World of Warcraft a lot of these players care deeply about their earned reputation, and the gameplay represents a huge chunk of their social life. I suspect that while these players are collaborating to clear a dungeon they are (emotionally) taking the gold and loot drops pretty seriously almost as if it were a real life salary on the line, but yet they're having fun.
