Keep an eye on the tires - due to the weight of the truck, they go all soft and squishy when you land a jump, which is pretty awesome for a video game.

I also posted a short blog post with my thoughts on the game here: http://william-hook.com/2009/09/15/lets-get-dirty/

Also, sorry about the quality...I don't have an HD capture card so I had to record it using my iPhone off the TV. :P (less info)
