2k6 takes a giant steaming shit on Live.
I constantly got pissed playing Live because it was so frustrating to even try to run a fast break. Guys simply do not run the break realistically, and they have to turn and stop running to catch a damn pass. That is completely retarded.
On the other hand, I am constantly stopping 2k6 to look at a replay of real life basketball being perfectly recreated in a videogame. It also seems like every time I play I see something I had never noticed before. The only major changes I would ask for in the 2k series are to make the ball get stolen more often when you try to put a ton of moves on a guy, and to make more dunks get blocked. Other than that, it's pretty much perfect to me.
