I downloaded the demo and shortly after preordered the game. If you like racing games, and have been a fan of Need for Speed, this is simply a must have.
It combines the older Need for Speeds with a taste of the newer Underground series. The demo includes 3 challenges. Each of which you outsmart the cops. The third challenge is especially fun(it gives you a Viper). You get to use the environments of the game to stop them, such as running over a doughnut stand and it falling on them.
Oh, something new to Need for Speed. Car damage. As far as I've seen it doesn't stop you, it can however, stop the police cars. Run one head on into a car on the highway going 140 and see what happens >=)
