Offroading game...?

Anybody know of any good off roading games? Not rally racing or truck racing or anything, but rock crawling and trail riding type games. Maybe one where you can outfit your Jeep (or other vehicle of your choice) with custom axles, gears, tires, and equipment. There probably isn't a game out like this but who'd like to see one??

Well, it seems like I've answered my own question. Too bad I don't speak Russian because this game isn't in english.

pure is a good racing game, you get to build your own atv and ride it and do tricks offroadtkdvenom

Sure, if you're 5 years old. Tricks are for kids. I want to be able to outfit a real offroad rig and take it across the Rubicon trail, through Rausch Creek Off Road park, that kind of stuff.
