I think some people are far too hung up on the bragging rights of the game, they can't be happy because of the whole premium thing, and lack of customisation...
Personally, I'm disappointed with what I've seen so far because I'm a massive BMW fan and was hoping for a better selection of BMW's.. no E30 M3 (so far)!!, I'm disappointed because of the lack of new real world circuits.... but at WORST this game is still epic, for people to overlook the massive wealth of content and detail this game offers, just because there are some gaps.. it's just short sighted.
It says a lot about GT and PD, and Kaz, that people expect perfection automotically...
GT5 has damage
GT5 has weather
GT5 has interiors
GT5 has a course maker
GT5 has far better graphics
GT5 has far better sound
GT5 has online play
GT5 has ~1000 cars
GT5 has WRC
GT5 has karts
GT5 has NASCAR
Sorry if you think you are being short-changed, I guess you could save your money and keep playing GT4 or GT5P.. oh no, wait.. sorry they don't have all these things!...
