I've just had my first play, up to the seconds race in Norway. I have to say I'm enjoying it tbh. It's not the graphical powerhouse I thouht it would be, looks lovely in places but a bit, I dunno, sort of cartoonish in others? Especially on some of the Indian tracks.
Handling is decent, very arcadey but that's not a bad thing. I've been throwing it round corners with my back end out and grinning when I nail it, so it's doing something right.
The AI isn't too bad, fairly aggressive I guess. I don't get the complaints that they stick to the racing line, why wouldn't they? They move off the line to pass you/others and stick to it when defending, in my limited experience so far.
I have to say I haven't found any of these magical invisible walls that some of the reviews have banged on about. I ask myself just how far off track they were trying to go, as I've cut a fair few corners and experienced nothing of this at all. Not too bothered about the penalties either, as most of the time it's my fault but I have had a couple of rear enders by the AI that caused me to get docked points - big deal, I lost a few points.
They have a good game at the moment, not great, but a few tweaks here and there as others have said and it good be very good.
