For one those REAL defensive schemes that you have video to show side by side!!
The fact that the AI adjusts to what you're trying to do, and the gameplan will be different each time, even from moment to moment during a game.
I think the biggest thing we loved about Inside Drive beyond the sim aspect was the fact that the AI was NOT predictable, and they not only made adjustments in game but took advantage of your mistakes with good basketball.
Its just that the AI was too good and never messed up really but the challenge was a pleasure.
I can't say enough how HUGE this stuff is. This is literally taking things to another level. In the past VIP was the closest 2k had to something similar to this but it didn't even work the way it was intended.
This is just next level stuff here IMO. I'd also say being able to change things via roster updates... thats the kind of stuff that is the future!
