Thanks for the comments!

I'm aiming for the feel of a satellite image (at least for terrain), so your first comment is great to hear.

I think the settlements aren't all that regularly distributed. They lie a certain average away from each other, true, but the actual distances vary by quite a bit. I suppose I should increase the density in the more central regions, though.

I think what may make it look too regular is the roads. I've been thinking that maybe I should make the road connections a bit more chaotic, but I can't really think of a rationale to do so. It seems like almost every medieval village is going to have roads to its nearby neighbors, right? But maybe the roads are too straight -- maybe I should introduce more twisty roads and paths to indicate unseen small streams, hills, etc.

The mountains are hard to do right. It's hard to remember how small the valleys get -- in other words, how much fractalization to put in.

Thanks again.
