Yes, it was the domes and tall towers as they remind me of minarets and byzantine churches and mosques. And eastern palaces. Although I have been running around 15th century Constantinople in this one game I've been playing very recently which might be why it sticks in my mind more. =P

By regular I mean that it just seems a bit griddy like if you lived in Iowa or something. =P It works and you can definitely tell what they are though. And I suppose some rice paddies are organised that way too so it's not wrong or anything. I was just thinking that if they were slightly less regular squares and rectangles. I am certain I saw a map here recently with an example of what I mean so I shall do some browsing.
