Burnout Dominator
Playing through the main mode is primarily about advancing through the seven different series of cars. In each series there are 4 different specific challenges, ranging from things like drifting a certain distance over the course of a race or taking down a certain rival X amount of times. These challenges provide a little flavor to the proceedings and as an added bonus each one rewards you with a new car. After completing all 4 challenges you are given the Dominator Challenge for that series, which gives you the Dominator car for that class upon completion.
The pacing is excellent and you will find yourself playing until the late hours of the night to earn that next car and beat that next Dominator Challenge. The lack of a crash mode in Dominator is a little disappointing, but it would only serve to distract from the excellent racing action that has always been the main thrust of the free downloads games for pc full version game.
You'll be hard pressed to find a better sounding or better looking game for the PSP. Dominator's framerate never misses a beat and the cars and tracks are all modeled beautifully, while the trademark sense of speed is as good as it's ever been.
