France in that period had a population density north of 100 / square mile, even in medieval times it was around 100 / square mile. Britain was about half that.

Also a fantasy map with large monsters in the wilderness wouldn't have as many cities. To be honest - to match the feel of the situation imposed by intelligent monsters you need to look at colonial America. Most of the towns and cities are on the coast or navigable rivers, with a few holdouts in the wild (which grew over time of course).

Also, almost all of France is arable land. Not all of Telzoa is, nor is all of Hokkaido that it is patterned on.

But the map does show how many villages there can be. I don't intend on naming every village on the map, that's not what I was proposing. But I was going to make a layer on the map that shows what land is actively farmed and through simple pixel counting make sure that land is sufficient to support the cities that are on the map.
