I race sprint cars and this is the best, most realistic game I have ever seen!
The graphics are fantastic, the tracks are realistic, the cars detail and reactions are very good. The only thing is that the cars dont do some of the nasty things that the real thing does, but that is to be expected.
One thing that may hinder some people's game play is that car setup is crutial to getting the car to work well and be successful (again, just like the real thing) and knowing the way the real thing works has help me immensly.
I give them a huge kudos for their development in this system.
