Summary: Now I never played 2k9. But have played 2k10 and '11. And I can tell you there not much different. I used to play 2k10 for Wii all the time; one of the best Wii games I ever played, but... Gameplay is not that much different between Wii and 360, but the graphics are obviously 100% better.
Summary: I bought this as a gift for my nephew and he really enjoyed it. I bought it once it was a year old and the newer version was out. He was young enough not to care about that and he had a great time playing it.
