Age of Empires III [SEP] Home Cities
"Age of Empires III" is the first game in the series to introduce the "Home City" concept. The Home City functions as a second city, a powerhouse that is separated from the active game. It cannot be attacked or destroyed, although an Imperial Age upgrade called "Blockade" stops the player's opponents from receiving Home City shipments. Similar to a role-playing game character, the Home City is persistent between games, meaning that upgrades gained through separate games can be applied and stay applied for as long as that particular city exists. Multiple Home Cities can be created and maintained, although each supports only one civilization.
