I just got my copy of NBA Jam in the mail today (Amazon B2G1)
I played 1 game to get used to the controls (nunchuck mode was awkward, went for wiimote style instead)
then played 1 campaign game so far using the Lakers.
2 Words..... BOOM SHAKALAKA
I whooped ass. It's a damn shame this game has no online.
edit: 2 games later I can say one thing about this that differs from the last games in the series.
The shove. Shoves are not affecting people in this game. if someone was about to shoot and you shoved them, then that would interrupt that shot. or if they were about to receive a pass and you shove them way before the ball gets to them, they would fall, and miss the pass. That is not happening here. They will just pretend you never shoved them and take the pass or continue on with their shot. it's a little frustrating especially when the computer can somehow push you while we are both in mid-air.
