Racing games have had a bit of a comeback recently. Codemasters are kicking every imaginable variety of arse with Dirt 2 and Grid. Bizarre Creations has 'Mario Kart for grown-ups' on the way in the upcoming Blur. And Justin thinks Sonic and Sega All-Stars Racing is the best thing ever (but he would). But it's been a while since a really crazy racer made a proper splash.
