I'm still on 2K11, gonna wait for 12 to get cheaper.
Also, from what I've heard 12 has too many bugs and stuff for me, want to let them patch it up a bit first.
I have a MyPlayer going with the TrailBlazers. He's a beast of a Center that inexplicable has the speed of Derrick Rose. Quite fun to run the offense with an inhuman monster. I've put up quintuple doubles more than once (because the inbound passing is retarded and makes it easy to grab steals, and the computer is woefully bad at guarding pick-and-rolls).
