I just found out about this awesome free game from another forum I lurk on. if you are at all a fan of baja type stuff or rock crawling, I HIGHLY recomend it. and did I mention its free?

the physics in the high speed stuff is not up to the level of say GT4, but the rockcrawling seems great. however I havent played a game that has better selection of vehicles than this, and really, is there any other game that has realistic rock crawling in it? the best part is that there is a community of people who create tons of vehicles and new maps for it! I just started playing it a few days ago and already downloaded a couple trophy trucks, a unimog 406, some crazy rock crawling buggies, series 1 landrover truggy, etc. there are class 5 baja bugs, class 1 buggies, a bunch of class 8 trucks, formula offroad cars, rally cars, lots of stock vehicles, and some wierd stuff like 1960's communist russian 6x6 trucks too. plus a shit ton of cool maps. the regular gameplay is a lot of fun too.
download the game from here, its about 529mb
