Impressive! I have to admit I didn't drive the previous version much, but this one really oozes quality all over. It's actually a pretty great layout for racing with GT classes, I find that it suits them really well, wonderful flow.
The only flaw in my opinion is the AI. They have lots of trouble with the kerbs and the walls, and they're really not that enjoyable to race against, especially during the first lap and with the mixed field.
