Gears of War II was one of the best games I've played on 360...lots of different scenarios and a good bit of atmosphere, especially in the underground levels. I'm waiting on that Arkham game, too...but I did get the MK v. DC game, just haven't had a chance to play it yet. If you liked the first Gears, you'll love this one, too...the last boss isn't nearly as hard as the last one in part one, but the sub bosses are a little tougher.
