What are Unique Units (UUs)?
Unique units are units that are only available to a specific civilization, and they usually were important in that country’s history. For example, Japan builds Samurai. Unique units replace another unit (the Samurai replaces the Knight — Japan can’t build Knights, only Samurai), but also have extra bonuses. For example, the Samurai has an extra defense point than a Knight. When they win a battle, if a civilizaiton hasn’t had its Golden Age, they will begin one.
