Played 2 hours of the demo last night. Was good fun.
Used a 360 pad, manual gears.
I'm overdrawn thanks to speeding and a couple of dings (where I'd been speeding ).
The only slightly jarring thing was the parking - the tough option just seems a little 'gamey' sometimes (no way would they really want it in those spots). I like the challenge of parking properly in the more reasonable spaces, but tend to use the overhead view for the slightly silly ones.
It's a bit tedious sticking to 55, though.
The speed is state dependant, in some areas it goes upto 65-80 think it's Nevada that has it higher.
I like the hard parking options, it's easy when you get the hang of it.
