Rover Run
 

Dont know if any of you guys have played this before but it is a pretty cool game, especially for you off-road fanatics. Its pretty much a game where you drive land rovers around and you add lifts, modify their gear ratios, etc, I found it very useful for experimental testing. No, i did not make this game, but i did find this while googling random google stuff its pretty decent but no audio =( the graphics are OK i play it in full screen at max resolution might be slower for others if you have a slower processor though mine runs at [email protected]. *NEEDS JAVA TO RUN*
Well heres the site anyways, the downloads are at the bottom.

I can get my rover to go anywhere on the first map with 95 foot-lbs of torque.
