Being that it’s now available for as little as £30 (apparently going up against Halo 3 wasn’t such a good move), I’ve posted a review of Sega Rally. I personally thought it was better than PGR4 which got nothing but top reviews and briefly lit up my friends list in the way that big new 360 releases tend to do, so I implore you to try the demo and jump in if you like it.
I had a great time with it even without being a big racing fan.
