In regular random map games every player starts the game with a Town Center. Until the Castle Age is reached, no more Town Centers can be built, unless the only Town Center is destroyed, in which case the player may build one new Town Center. Up to 15 Villagers can garrison in Town Centers for shelter from attacks. By doing so, they give the Town Center an attack (arrow fire). This way, players can survive and fend off early attacks. Archers can also garrison in Town Centers to give it an attack. Town Centers cannot be converted.
