This game was my first ever PSP game, and I was blown away by it when I first played it.
Gameplay: Really fun, blowing up car has never been this fun, and each character and his/her car have some sort of storyline that adds to the enjoyment of the game, because I think racing games should be like this, Car combat sort of thing.
8/10
Graphics: Like I said I was blown away by it's graphics, I couldn't believe what I seeing seriously, there was a time between 2006-2007 where I just played handhelds because I didn't own any next-gen consoles, and the only system I had than was the Gamecube, so you can understand how impressed I was.
9/10
Storyline: Every character has some sort of storyline which is a plus to the game I guess.
8/10
Conclusion: You can probably find this game for pretty cheap these days, and if you do, pick it up, it's soo worth it.
