I've played a few hours.
The new camera.

The improved build/buy mode (a search feature FINALLY)

The load screens

Only having one empty lot available

The improved interactions
So I dunno how to feel. It's not half as bad as people are making it out to be, but it's not worth $60 either. Maybe I'll look into it when it's packaged with an expansion pack and on sale.

I feel like they improved a lot on the non-gameplay elements (build/buy, AI, etc) but took away from the gameplay itself to accomplish that.
