The only complaint I had about 2k11 was that they reduced the number of PC USB controllers from 4 + 1 keyboard (2k10) to 3 + 1 keyboard. That's ridiculous, locking one controller exclusively for someone using a keyboard. No one in this day and age uses a keyboard to play this game, and if you did, get a job at McDonald's and buy a $10 gamepad. I used to love having my friends over and having a 2 on 2.
Anyone know how many controllers 2k12 will allow? If these developers weren't so hung up on crap consoles, they could allow full 5 on 5. A PC can daisy chain over 150 USB devices. Hell, I should be able to have someone controlling the ref or the guy selling popcorn in the stands.
