The court looks small to me. The distance from each basket on each side seems to close together. Other than that, game looks like a good remake.
I used to love this game when it first came out on the genesis. I actually bought it on release day in 1994 (ish - I think that was the year)... I swear the retail price was $70 for brief period of time (similar to what they did for Mario 64 when it first came out). My buddy and I would rush home from school and play this thing for hours. We even fell for the enter "MVP" and win 200 games and Michael Jordan will be unlocked trick. A dream come true for a group of friends growing up in Chicago!!! I won 235 games (or around there) before the system stops letting your win total move up any further. This does not work by the way - for those that didn't live this same memory :-) ... It was a fun quest for us in any case. The only other game I can remember us being nearly as excited for was Mortal Kombat (which was only able to compete for our teenage attention due to the never-before-seen levels of violence :-)). Anyhoo, awesome game and I hope they do it justice!! For others seeking a similar experience, the NBA Street series is really well done. Volume 3 on the Playstation 2 is super cool (as were the earlier versions). None will ever compare to the original NBA Jam though - it has that "you had to be there" part of your childhood nostalgia factor that can never be recreated.
I think the gestures might be awesome, especially since it's an arcade game. But I hope there's a buttons only control scheme too.
