Decent game and is pretty fun, only problem is the glitches, sometimes when leading race and you win in 5 laps, the game scores you as 4th. Kind of annoying when you are trying to upgrade your cars Other thing I do not like is the fact that a couple of the dirt tracks are awkward shaped, not sure what dirt tracks the creator goes to, but we dont have any in my area that look like that. This game has a load of potential for an iPhone game, hope there is an update soon.
