If you own a psp, do yourself a favor and buy this game!!
The graphics are amazing. Simple as that. You will be blown away by them.
The gameplay is incredible. The sense of speed is amazing. Especially is you are playing on the hardest level. Definitely the fastest game I've played.
The sound is pretty good. I'm not a fan of techno but the soundtrack just mixes so well with the game that it is hard not to like.
This game is definitely worth the $40 you plan to spend on it.
At first, you will think that the game is really hard, but the game does a very nice job preparing you for the harder levels.
Overall, I think it is a superb game that blows away most other psp games.
