Ok so far my breakdown (based on the fact that this is not the ratail version, difficulty level seems to be Rookie, and Game Style seems like default not simulation)
PROS- CPU Double Teams are back!
- Spacing seems improved
- Passing seems a lot better than 2k12
- Jump Shoot animations looks even better than 2k12
- Nice contacts on the perimeter and on some drives
- Dunks looks great not more floaty dunks
- Seems like a blend between 2k7 and 2k11 which is great for me ^__^
CONS- I'm not seeing enought contact in the paint but that maybe related to game style settings
- Rebounding :-(
- Graphics Engine is outdated....but I guess we need to wait till next gen consoles for this
