I'm playing it these days. Very good game, graphics are well below GT3 ones but it's got very good gameplay. And despite the fact it's got a lot of cars less than GT3, it has 4-5 different Alfas, 5 Fiat, lots of Mercedes and other European cars, which, when GT3 had 1 Alfa, 1 Fiat and not even of the best ones, seems to me great. I mean, you feel it's got more cars than GT3 even if it's mathematically wrong.
Bad tracks, but good AI, sure worth playing, anyways.
