Newest in MX gaming technology... Mx Simulator.
Beware... this game is not easy to get used to. I could go on and on about this game but I'll keep it short. first off this is a PC game, if you have a slow computer you may still be able to play it, but only offline with stock track no computer AI and with your graphics turned all the way down. But the reason this game is unlike any others, is that it was made by a single person. However it is constantly updated by not only him, but the Mx Simulator community as well. The game is only $42.00 USD... I say that is worth it for the hundreds of HD tracks that have been released that are totally free for you to download. Not to mention that any time new gear is released in real life, someone will make it for this game. You have literally thousands of gear styles to choose from. All the 2011-2012 bike are already released, with countless graphic styles to choose from. There are always players online to go play with. This game provides limitless entertainment with a physics engine unlike any other.
