Many of the buildings in Altis and stratis are too uniform, and look untouched by time. Looking at Kavala on Altis, as amazing as it is, the first thing I notice is the sea of red roofs and uninhabited looking cookie cutter buildings. While a small town may have similar buildings, (as seen in the real life comparison images of Greek towns) I can't imagine a city of Kavala's size was built in such a short span of time by the same contractors to the point where every single building looks newly built and exactly the same. Even something as simple as adding a few building types with different colored roofs, or faded paint, or cracked wallpaper, etc. would do wonders for immersion and visual appeal.
