nba 2k10 seemed to be to complex for the psp system. Too many moves were used for the same button. I never got a block shot ever. the good thing about it is that the roster is updated with the true players. Other words, not too much good about it, and a lot of bad.
For those looking for a great NBA experience on the go, look no further. I was very surprised at the amount of depth this game offers with the Association mode, and if you're familiar with NBA 2K basketball games, you'll feel right at home.
Not having a shot stick during the normal flow of play (you get to use the analog stick to shoot on free throws) may be disappointing for some, but for me it was a non-issue since I'm old school and still prefer to use the button to shoot.
Full commentary, instant replays, ability to call plays on the fly, there's not much missing from this excellent port of the PS2 version. I also feel it's worth mentioning that this game has an excellent soundtrack too.
Overall, a worthy addition to your PSP sports library.
