....as far as free PC games go. I came across this a couple days ago and think it is a totally cool game. Imagine a free 3D game where you can freely drive, Big rig trucks, trailers, Bobcats, cranes, custom rock crawlers, muscle cars, boats, planes, jets, tow trucks, bikes, fire vehicles, police cars, military vehicles, and everything in between on any terrain you choose. Sounds cool right?
Just check out some of the things they have out there!

As you can see I focused more on the crawlers of the game, but there are so many other vehicles you can choose. It acts just like a simulator, in which everything reacts as realistically as possible. Now, if only I could get it to work with my system I'd be all set! :)=) Here's where you can download it. You have to download the main game which comes with a few vehicles but you can add to your collection by downloading other vehicles/trailers/landscapes ect. separately.
