Great fighting game, don't go by the Gamespot review score.
The combat system in this game is fantastic and incredibly fun. You really cannot go off of vidoes of the game in action as the game looks and feels much better when you are actually playing it. The online mode is pretty much perfect with a fantastic spectator mode. There are also tons of unlockables and customization options for your characters.
I pretty much could have cared less about this game until a friend of mine, who is really in to fighting games asked me to get it, and I have to admit that its damn good. This game will also be featured at the EVO competitions this year and rightly so-don't go by the reviews-heck, even if you are mostly in to single player, the game still has a lot to offer-call me surprised-great game!
