I can't recommend DiRT highly enough.
After playing the demo, I wasn't sure.
I thought it may get a bit boring, wasn't 100% about the handling.
The full game though is just brilliant.
Far from boring, no problem with the handling, some of the tracks are truely breathtaking in their beauty, runs fast, no slowdown, and I think in the 75 races or so I've completed so far, I may have seen 1 incident of tearing.
Saying that, I've also orderedSega Rally as I enjoy that sort of game too, but, if I had to choose, I prefer DiRT, graphically, and handling wise.
I don't know what it is with me and the Sega Rally demo, I really seem to be having problems with the handling. I've played previous versions of Sega Rally, and loved them. I'm hoping the full version improves the handling, as I'm finding it really frustrating on the demo, can't win at all on anything other than the bumper cam.
