I know that it would overlap, but I kinda want a realistic empire, like Canada, which has only 3 big cities (which would be by them self 80%-100% untocuhed), quite a few medium cities (which would some what overlap, but most squares untouched 60%-90%), regular cities (40%-60%) and then heavy populated areas (where just almost all squares are being shared, and you basicly run 3 farms, and a bunch of specialists so 0%-40%). that way, it gets real mix of cities, and when conquering a new area, its not like you get one city, and all of german fall (like in the Earth 1000 AD maps). jsut really wanted this for a long time (since i started playing civ 4)
