Gamesrating.com Awesome game so far. The basic premise is that you get to race diferent american and rice burner cars off-road, in snow, uphill, etc.
You would specially love it cause you get to drive your WRX, and its a sweet choice here. You get to customize stuff like tires, suspension, etc.
The driving physics are realistic, you cant just accelerate all the way to the finish line. Its easy to lose control, specially on snow.
Very nice racing game. And the graphics are sweet.
