NBA Live 06 for the PSP is best portable Sim B-Ball ever..
If you go to back to days and point out which portable basketball is good you'll say none. With the PSP things are about to change. The graphics are like playstation 1.5 for a portable thats pretty darn good. The sound is very accurate. The soundtrack is awesome. The gameplay is great down to the control is very responsive. Has every its big brother Season & All-Star Weekend, etc. You have REAL ONLINE PLAY but with a fee!!!! Its pretty slow If you or your opponent has slow connection. There are items to unlock also. There's a flaw that comes with every Live game and thats little glitches here and there. Like: You can't block a dunk, when you'll under the rim and you shoot it'll end up hitting the backboard or out of bounds, Com hitting threes like a manic and whom ever the PG is for the Com that player will hit more than 25+ pts a game always.
I purchased this game from Gamestop for under $20 bucks. For more updated roster,graphics and hopefully fixed this glitches than get NBA Live 07.
Enjoy.
