Arcade is full of corker games and nobody has mentioned DUST yet, what a stunner of a game that is, its like metroid met anime and had a baby, and it rocks, the voice acting is better than most of the so called triple A games. Also for people who like stuff like castle crashers etc why not try DUNGEON FIGHTER, its huge with massive amounts of equipment and skills to unlock and upgrade. I must have bought about 20-30 arcade games from xbox last year and theres still stuff i want.
Last week Shogun came out and thats the next one on my list of purchases as the demo was great also the cave will have to be snapped up soon as well.
No wonder its revenue doubled, if you cant find something good to play theres no hope for ya.
