It is MUCH more responsive, at least offline. The players can take small steps and it makes all the difference in the world. The whole game feels smoother and faster, and there are new movements on offense and defense to give us more angles with which we can attack and stop an attack.
Presentation has taken a GREAT step up. There's so much work done in this game that it's mind blowing. I know 2k is a triple A company and title right now, but it's still amazing to see this much work go into a single, less than a year cycle.
