Yay! I really like this; I was looking forwards to it for a long time.
However - as someone previously stated in this forum - the new city overview makes your city look pathetic and weak. I would really like if the building design would be completelly overhauled and be designed - from scratch - to fit and be seamlesly integrated with the new overview. Some buildings just don't fit this - like the Wall. Plus (as many people have said already), now that we have a large overview, we can have larger city are for the people to live in. Also, since there is such a large water area, I would appreciate if there would be some traffic there depending on the Harbour level: at level 1, there are few fishing boats, at level 10, you have some fishing boats and very few large ships sailing in and out of your harbour, and at level 20 you have mainly large ships sailing in and out of your harbour very frequently. And if there would be an attack on your city, you could see the enemy units ACTUALLY attacking your city.
