people on the 2k board are raping this demo, but I think this demo is sweet
I like the gameplay a lot, the controls and what not are a lot different than 2k7 and it took awhile to get used to, but the AI is brilliant, they rotate a lot, if you leave somebody open on the perimeter to double team, the AI will find him and he will drill a shot to make you pay.
The gameplay just seems very good to me, comparing it to 2k7. The AI is very smart and the gameplay may not be as good as 2k8 will be, but I may put my money on nba live 08 (after gamespot reviews and input from non-biased users of course). Even if the gameplay is slightly a step down from 2k8 (I say it's good in the demo), I may buy it just because it'll probably be more fun to play with all the dribbling moves and post moves you can do.
PS.
You should post some videos of the actual game instead of practice.
