Played around with it for about an hour last night. Just started from scratch, didn't transfer GT3 money/licenses. Am running a lightly-modified used '90 Supra with 301hp. Wish I could figure out why the damn thing is plowing like it was FWD though. Can't oversteer for the life of me.
Overall, it's good. But not hugely different than GT3 -- which is the consensus of every review out there. AI is still as bad as ever. Graphics are great in replays, but when just racing I'm not noticing a significant difference over GT3 except for the specular lighting effects at night. But so far I've just raced old GT3 tracks, so perhaps there are some more that are more optimized for GT4.
