Recently been adding map modes to my CCRP-inspired strategy game. Currently, there are three: Political, Diplomatic, and Yesedr. I intend to add more, such as Trade, Population, Culture, and Religion, among others. The political map mode displays countries and their borders. Diplomatic displays the country selected in green, its vassals in purple, its allies in blue, and anyone it is at war with in red. There's now also a terra incognita feature, so you can only see your nearby area. This will eventually support exploration/colonisation. It's still a work in progress though, so it looks a bit rough
