Good one The single-player story is focused around taking over and defending territories. Each territory has a number of individual races, and taking over more than half of them will earn you the territory. After you're in possession of a territory, other crews will occasionally try to take them from you and you're prompted to compete in a defending race. This whole system is reasonably cool in setup, though since you're allowed to retry any race you fail you're never really in much danger of losing anything you've earned. It would have been cooler if you couldn't retry, giving the whole scenario a more back-and-forth and dynamic feel, though that doesn't quite fit in with the game's very arcadey setup.
Rented it out I'll be buying this copy when the US version is available. I had in on XBOX 360 and loved it, and i rented it for my ps3 the other day and got through 75% of it... love the game, its hugely re-playable. Graphics are wicked, but I have so say, just a little bit more jaggies are visible in ps3 version and frame rate suffers at times, particularly in multiplayer.
