That would have to be the best and most realistic driving experience you can get, with a realistic chance of winning, unlike TOCA. But a game that actually requires the use of brakes gets my vote automatically.
Although there is no car damage, I like it that way, as I would not like to see my Team Oreca Viper GTS/R with a dent in it.
If you have a boring few hours coming up, keep yourself keen with an endurance race or two.
This is an excellent game and driving experience. Reccommend it to anyone.
