I just downloaded it today I love the concept the sound of the car's are very good it's not tiny and the greatest thing are the variety of car's mind blowing. The only thing that I think need's changing is the speed I mean the (X2_speed) it should be the speed up option not the standard speed. Slow it down by one to keep the realism. It's the only reason I gave it 4 stars but it is a 5 star game five.
