Any final suggestions?
I am quite happy with it
Yeah keep this one. I dont see why you change your creations that much.
They are a masterpiece from the beginning but you keep changing it over and over again.
Progress will then be slow and it will take ages to fill all the gabs.
It would be better to make a city style for; EURO, ASIA, AMERICA, MED and MID for the years WW1, WWII, ColdWar, Modern. Those are despritly needed, but that is my opionion.
Once more... I like you creations! But... stop changing them!
