I've only played about 4 hours total with a friend at his place but his comments were basically that its streamlined in places it needed more depth. He told me you basically have to keep making new cities because you bump up against the limits so often and because the games mechanics break down when you get to that point. My impressions were that outside of the visual upgrade and some quality of life UI improvements, it is a step back in many ways. It seems like EA corporate had their grubby mitts all over it, you can already see the monetization chain starting - bigger cities, transport upgrade pack with subways, etc.
He ended up charging back his credit card yesterday when Origin refused to refund him. I feel bad, he'll probably get that account banned and he had like 10 games on there but oh well, they lose a customer for life if they go that route.
