I could've done without Nurburgring Nordschleife. For all the work that I know went into it, we could've had 2-3 classics like Midfield, Apricot Hill, Seattle, etc. I would've reserved Nurburing for DLC.
I also would've passed on Madrid and London. I understand wanting to have a balance between circuits and city tracks, but I think if you polled most of us, we'd rather have had El Capitan and Red Rock Valley or SS Route 11.
I like Cape Ring, but it is over the top and way too long. It's kind of like a metaphor for GT5... they tried to put just too much stuff in, but failed to execute it all properly, in the end it could've been even better if the sights were set a bit lower.
I also didn't see a point in rendering the Top Gear Track if it's near impossible to unlock.
