Unlike a lot of games with in app purchases, this game doesnt take a lot of money to really enjoy. A standout feature is that when an upgrade vehicle is unlocked, the game lets you sell your old car back and get all your money out of it. Real racing physics make it a fun and challenging game. Wish there was an option to customize the vehicles with paint and graphics, wheel and tire changes, and accessories. Otherwise, one of the most addictive and low cost games to play if you a dirt slinging, dust breathin, off road junkie.
