I'm enjoying it, taking everything into account it's pretty much what I expected it to be. I like how the islands have turned out, in some ways despite me saying so before the game was released I quite enjoy the Casino when I ever eventually go to it. Apart from a few select cars the handling doesn't seem too bad to me either, it's far from realistic but it's fun and easy enough to get used to. Also, from my experience the servers seem stable and I'm always connected to at least two other people, there's never any lag apart from when I come across someone who does just have a rubbish internet connection. I've yet to try the Social side of things because I've just been ploughing on throw the championships to earn some money. Performance is fine, I was running it with the graphics on Medium until yesterday when I tried out all the settings on High and I dare say the FPS has improved slightly, but it was fine anyway. I'm finding the game has a lot of re-playability as well, despite some of it's pitfalls (how easy it is to win) mentioned in the next paragraph. I've yet to meet up with anyone from these forums for a cruise or a race or anything else but the game's keeping me on my toes well enough, I've still got a few championships to go as well as most of the driving missions and multiplayer side of things so it should keep me occupied for a while yet.
The things that let it down for me though are the lack of a properly functioning clutch and brake pedal although I'm expecting those two issues to be resolved quick-ish. One of the main things that annoys me though is the story line aspect of it and the characters. These stupid phone calls I keep getting saying Miami, Ryan or Stuart want to race me to prove themselves and they're even silly enough to bet their car are getting on my nerves, I've read that I can't sell their cars if I do win them so I haven't accepted the phone calls. Surely they should get the message after 28,000 declines of their invitations to race that I don't want to show them up any more after beating them silly in every championship thus far. That's another thing, I've yet to lose a race or even come close to it, even in A1, it's a walk in the park. Tess regains some respect with her constantly wobbling breasts though, someone was paying too much attention to detail on that side of things, lol. The commentary at the start of every license and race wears me thin because there's only a few phrases they use and after less than one championship or license you've heard them all. The licenses are all pretty easy and samey as well. "I know! Let's give them a faster car and see if that makes it more difficult for them" - Not really seeing as the faster the cars get they generally handle and grip better as well.
I've probably missed some things out but overall I'd probably give the game a 8/10.
