Not bad if you're a fan of the series

User Rating: 8.8 | Need for Speed Underground Rivals PSP
This game really is a good game if you are a fan of the series. EA managed to make this for the psp, and it works. The urge to unlock everything makes you want to keep playing, a definite if you like the other NFSU for the consoles. The game play starts to get challenging near the end, but it still remains fun. The cars look really good with all the different customizations. If you have a friend to play with, of course the game will have more replay value. One mode that some people tend to have trouble with is the drift attack. Once you learn how to do it, it becomes one of the funnest things to do on the game. The nitrous runs are extremely fast and the later ones become VERY challenging. The bonus upgrades for completing on gold are well worth it too. And the car management and upgrade system works very well.
