I would buy DLC in a second and honestly would probably buy it even if it was just more of the same. There's a lot to complain about but when you get right down to it the game is still fun to play, which I think says a lot about what they did right--and I haven't even tried online yet.
Fun. The magic ingredient that a lot of people miss in games that are not mega blockbusters. This game has fun in spades.
