"You see, while it is true that people enjoy being a dick in games, it stops being fun when the game actually wants you to be a dick. It's less about dickishness itself and more about defying the rules. That's why it's more fun to be a dick in, say, Half Life 2 because the game is desperately trying to make you out as the hero even while you're jumping on someone's head throwing broken bottles into people's eyes."
