This is an amazing, fun app ( You should add sprint cars ). My family loves to race because thats what we do and I love this game. What would make this game more realistic would to add pits and to where you can pull of the track. Another thing that would make this game fun would if you added more drivers like Terry Phillips, Ryan gustin, Jonny Bone, and Scott Bloomquist. With those drivers it would make the field of cars more competitive. ( It needs a larger field of cars 12-15 ). Also add more real life tracks like Eldora.
