I was watching Attack Of The Show last night and they had this game showcased, looked excellent, so I decided to download the demo.

If you've got a PC that can run this, and love arcade style racing games (it's fast, stunt style tracks and beautiful settings and graphics...you'll love this game.
Download the demo and let me hear your thoughts on it, I'm waiting for a release now so I can purchase the full game. I'm hearing 4-8-05 for UK and MAY (ugh) for US.
