For the next version I definitely have to add a few more empires, if I can get the data.
Definitely missing more bronze age players: Minoans, Myceneans, Hittites, Indus Valley, Shang, Babylonian.
Also missing all the precolombian american: Aztez, Maya, Inca, Olmec.
...and the great african empires: Kush, Aksum, Ghana, Ethiopia, Mali.
Finally I should split the chinese dynasties better and include Ming, Qing as separate from modern China.
Korea and Japan probably deserve a spot.
That's 19 more! It would take us to 45.
If we add France, Portugal, Dutch... 48.
50 should definitely be a hard limit. Space is limited and we don't want it so crowded that it's illegible.
