I'm not a fan of huge maps (because I don't have the focus / concentration / yearning for massive amounts of micromanagement for huge games), but this one does look like it'd be a lot of fun. Started a game as Pangaea, running my harpy scouts over to likely looking places of power - Zhentil Keep, etc.
Nice job with the places of power especially.
This map does highlight the need for the ability to change the color of the lines for the "neighbors" filter - both because there are no real boundary indications in the source map, and because the current color blends in with the map.
(And actually, to be able to have a small displayed icon for the central point of all provinces would be great too, and not just for this map - Urgaea, among others, has some provinces that are difficult to click on because of irregular shapes.)
