Very interesting. Regarding Thasos on the Greece prototype, judging from this version, I'm sure it's just a rough idea of where he was thinking he'd like some centers and that he would refine as he developed the powers. I have a very early stage but abandoned Ancient Greece variant I was working on, and was trying to put 10 powers in roughly the same area. I had Sparta, Athenae, Knossos, Rhodos, Miletus, Troia, Byzantium, Pella, Larissa, and Ambracia. Basically five powers encircling southern Greece, and five powers encircling northern Greece, but many of the territories are similar to the ones here, so it looks somewhat similar. Thanks for sharing.
