So I made this a few weeks ago for my final project in ancient history class. It was slightly hellish and took a long time. But it's actually completed now! So, please enjoy!
By the way, if you can beat Egypt on hard, go brag in a comment! Only three people, including me, have beaten it so far (the record is two tries).
Prehistory: Running with Wolves - Korpiklaani
Mesopotamia: Pine Woods - Korpiklaani
Egypt: Fatal Xihupohualli - Tenochtitlan
Troy: Path - Apocalyptica
Rome: 2012 - Tenochtitlan
China: Epic - Tang Dynasty
Japan: Japanese Traditional Music - Koto & Shakuhachi (I guess that's what it's called? I don't know...)
