The African and Artic maps are mainly there to add more set-biome maps, i feel we already have many random biome ones. Also they look interesting.
We have few maps of dryer coasts(carthaginian, libyan, egyptian) so thats why Carthaginian Coast was created. Historically, control of it was important for protecting the Carthaginian trade routes. This map is similar to Phonecian Levant, might need some extra modifications.
The Danube was historically an important river, seperating kingdoms and tribes. It being an easy frontier to defend, its shores were contested for. Also we have no maps with set autumn biome.
India definitely needs some extras, but could be promising. In ancient times the Mauryan Empire warred with and conquered the tribes inhabiting this area.
The Two Rulers features an archipelago in the Agean Sea. Ancient Greek city-states often only controlled 1 island and were also frequently at war with the neighbouring polis.
