Ugh, i've given up on bball video games. They are NEVER realistic enough. The movements are eithr unresponsive or just incredibly choppy and certain animations are performed over and over again when they shouldn't be...especially closer to the hoop. I'm just speaking generally, I haven't played either of the 08's. But I don't think they'd change my feelings.
just check out ign.com and see what they say. i trust them.
