Well, some of the air juggles are changed. And some of the moves have different notations and properties now. It is a good time to relearn. In term of gameplay, other than online, I really have no complaints, even for Scenario Campaign. SC is not that bothersome, can be completed easily, and short enough to be a minor distraction only. The meat is the single player mode. I really treat this as a training ground to get better so that I can go arcades and kick asses Learning Bob now, he has lots of fun moves ;p
