Codemasters today released a demo for GRID on the Marketplace while PSN and PC demos are planned to go up later this week. Here are some images and a video from the quite impressive demo. As you will see in the video, the AI is pretty rough and won't hesitate to use heavy force to go past you. As you play the demo, you'll see that the game is more Arcade than sim - meaning that some people won't like the way the game use drifting, but personally I like what I've seen so far.
Update: First video is up, one lap in Germany.
Update 2: Drifting event in Yokohama!
Update 3: Let's be done with the best looking track of the three: San Francisco. I'm sure the fans of MSR and the first PGR will be delighted to see that track!
