I have not had much time with the game. The good first grapics and sense of speed is great and it works fine for windows 7 64bit with no issue. I do have a few issues with the game though despite the good sense of speed sometimes it moves to fast for its own good and sometimes your driver will hit a leaf and crash out. Sometimes he will hit a cactus and live to tell the tale. Slightly annoying. Invisible walls abound inside the track. You wont see them but a respawn be coming your way if you hit one.
Got this for a the Price of $1dollar so I am not complaining. The music is hard rock but I like it however its a little loud on default settings. Other then the invisible walls, and leaves killing my rider its a fun and good looking game.
I do have one other nitpick the pick your own parts for your bike is junk. It takes away at least as much it replaces. Now I understand why they did this its for the online play to keep it all fair. However why even offer it? It seems like a waste and not very well thought out. Also the online portion for the pc is now dead and buried. So its a waste of resources even bothering with this option.
