Hmmm... I just tested the map. While I'm very glad that you shared it I'm afraid that it's not on my personal top ten list. Yet.
It's a very beautiful map, and the concept of warfare across a "fused earth" is appealing.
I'm curious why you choose such massive borderlines between the regions. It almost gives the impression of a landscape covered with thick veins, especially since you shade it with red. Your approach works well with the water provinces though.
The map is almost completely free of barriers and chokepoints. Which is logical since the whole concept is a great big continent, but it makes the map feel a bit bland. I would love to see a scenario based on this map where overpowered independant forces are used to "wall off" sections of the map.
