To make this mod more focus on the most important powers at the medieval time, I made a new civilization list this week. The following is the list:
Eastern Roman Empire
Anglo-Saxon Kingdom (England)
Holy Roman Empire
As to the first draft, I deleted Spain, and added Goths, and Slavics were specified to Bulgarians. Venezia is a representative of all italian states and papal state, so it will still have unique units from all over the peninsula, like swiss guard which serves for pope.
The ages after age3 for Huns are correspond to the Hungary's history, although it is still an argument going on about how hungary was related to huns.
As a result of cutting Castile off, there are 4 civilized nations remained:
Eastern Roman Empire ( Roman Empire/Hellenic)
Venezia (Roman Empire/Carthage)
Persia (Seleucid Empire/ Parithian Empire)
China (Chou Dynasty/ Han Dynasty)
The ancient nations mentioned in the parentheses are the nation to revive. If you still don't get that, you can look at previous news.
