Same style of layups and dunks kill the game, same blocks same crossover spins- all the things are same,Live06 is far far away from reality!
I want a variable animation system. For instance, when going for a layup, instead of pressing the dunk/layup button again to adjust the shot, utilize the right analog for mid-air maneuvers, like pressing down in mid air will cause you to double clutch, pressing up will give you a finger roll or high arc layup, pressing left with the ball in your right hand will switch hands, and pressing right while the ball is in your right hand will be avoiding a block. Of course, you should be able to combine them. They can call it Freestyle Superstar Air.
Freestyle control should have more combos like double taps and streetfighter/mortal kombat type combos. Bad ballhandlers should have slower, less fancy dribbling moves while better ballhandlers should have quicker, fancier moves.
I would like to see the pro hop modified to allow you to pick up the dribble while on the move and start your two steps, maybe when your press turbo. From there you have a choice of passing or shooting, or traveling.
Add a sweat layer(for glistening/wet look) to players based on fatigue/time played, and sweat particles for dripping sweat.
When you are closing the passing lanes, the AI of the computer players should be smarter and make cuts to the basket, or when a player is open cross court, the ballhandler should drive in the lane and kick it to him or make multiple passes around the perimiter to get the ball to the open player. Summary:better off ball movement from the computer AI.
Implement the Havok physics engine(or make their own), and tweak the ragdoll effects, combine it with collision animations to create more realistic and variable collisions.
