Just note that the two maps are not exactly the same. The one noting the region names generally includes some water around the land masses so while it kind of looks like they have changed the land masses are the same, this one is just showing who controls that area kind of thing.
Also remember that this is a world scale amp only showing up areas of considerable note. There are going to be a lot more forests, scrub etc when a more local map is done for a region but if I did that on that grand a scale then I might as well nearly paint teh whole map in forest adn scrub and be done with it cause area's around towns that have been cleared would be hardly noticeable a the world scale.
Oh and yes I can add some more volcanoes at some stage.
