Summary: First off, my biggest complaint about the game is the precision shooting. Why not just press the button once and depending on a few variables (openess, players ability, or distance to the rim) the ball will go in or out. Instead you have to press the shot key twice. Also a turbo key would have been awesome. I don't think it is too much to ask as I recall the NBA Live games on PS1 had a turbo button.
Summary: About the only thing this game will do is show you the potential of the PSP. The game itself has nice ideas in terms of setting up plays but falls down in the implementation. Why setup a post play that's 50% effective when you can jack threes all day and hit just about all of them? This game is a rental at best. A very short rental. Also, it does not come with commentary of any kind except when the announcer goes through the starting lineups.
