Ok, played it for about 15 minutes on lunch.
Initial impression:
Graphics are amazing. Considerably better than Forza.
Physics model, pretty odd. I found myself doing long fishtails trying to recover from a slight skid. It felt like there was a delay in the steering causing me to overcorrect. Cars seem to turn much sharper under braking than while coasting. I realize there is some weight transfer but this was just rediculous.
I won’t pass judgement on it until I have some time to drive more than one car etc. Hopefully the physics issues were mostly because I only played for a very short time.
