Getting really damaged seems like it would kill the fun, but this game has one unique feature. You can rewind the game back to point when you were driving good and resume from that point. You can only do it a few times in a race so it isn't something to depend on. This also allows you to watch pretty cool replays you can fully control.

Very realistic racing with crashes that can total your car. You take damage which can affect your driving ability. For the most part, unless you total the car or really screw it up, it's still fun to drive. One funny example of the realistic damage affecting the driving. I was watching a friend play, he crashed into a wall and ended up screwing up one of the front tires. It got jammed so the car would only drive in circles unless you really fought it with the controller.

Awesome graphics with very realistic graphics right down to the damage. This game is probably the closest to Gran Turismo: Prologue so far.
