It's pretty amazing. Online games are fast and quick to jump into, the only problem being that you start out at the lowest rank and end up completely demolishing everyone for the first few hours of play until you get to the high ranks.
It's the only version available on PSN, and I'm pretty sure it's exclusive, so yeah.
It has good graphics (wish the play box were a tad bigger) and is simple and clean. No cartoon characters or bright visuals, going with sleek and dark backgrounds was a great call. It's just the game. Plus some great new modes.
