Sombre: I've made the mistake before of drawing province borders and saving a map image before thinking about how people might actually want to play the map. I prefer high province density myself. With this, the borders and province definitions will be the very last thing I do so we'll have a version with ~150 provinces for you and ~500 for Aezeal.
Personally, I don't like the idea of including sub-maps as part of the whole and I'm confident I can strike the right balance of wealth and aesthetics even if certain regions have to be more tightly packed with provinces. This, of course, doesn't preclude other independent maps focusing on some of the WHF campaigns, as you suggest. If doing this big sucker doesn't burn me out, I could follow up with a separate and smaller map of the Old World or Lustria.
I've read a couple AARs from those all-mod games and it's been a hoot to see how each of the nations is faring.
Thanks for all your work tweaking my nations for CBM. As for my Dom2 nations, I have no plans at the moment to bring them over. If you've got the spare time, you also have my full permission. Come to think of it, I don't even have the files for Necropolis on this computer...
