For NBA2k11 not really....
How about every court on each NBA team's homecourt is different, plus their practise courts, a streetball court, Summer league and D League courts all with their own atmosphere with dynamic crowd levels. Every NBA player has the likeness of his real life counterpart. I would say modelling a human to look like a real person is quite a lot harder than modelling a car and there a lot more players than cars.
Tons of motion capped moves and plays.
The usual instant play, season and play off modes, multi year franchise mode that has the depth of a soccer sim management game, my player mode with indepth player creation that rivals the Sims and then some, and post game interview with actual speech, the newly added Jordan challange mode with a virtual Jordan that looks and moves like the real person.
Plus game commentary and presentation that looks like a real TV broadcast etc etc etc. There is a ton of things to do and see for a yearly game
