One of those must have games
First of all, the game has a great story behind it. You can access three cities by completing different races and tasks with help from mechanics and designers at the "Garage". They talk to you in monologue as you just sit there and stare at them, not saying a word. They tell you about your new cities, cars, and special moves. Depending on the type of car (there are SUVs/Trucks, Tuners, motorcycles, and many more), you can take advantage of different power-ups. For the trucks, there is a move where you can destroy anything that you run into for about 8 seconds. This comes in handy when you are trying to win a race and the traffic is overflowing the racing streets.
Another great feature is the many costumization possibilities a car can have. License plates, decals, and neon flashing lights are many items to play around with to make your car or bike look great while riding in the city or racing.
This game basically is one of the best for the psp because of the fun depth it has. It is a must have game for the psp, a sytem that lacks good racing games other than the "Burnout" series. Whether it is Detroit, Atlanta, or San Diego you are venturing, the game could take about 36 total non-stop hours just to beat. With much practice, you will be conquering every race the game has to offer.
