Cities
Cities are the centers of population, production and power. When founded or captured, a city is assigned to a Family.
City sites
City sites are the only locations where Settlers can found new Cities. A city site can be claimed by a Nation as long as a unit is located on it.
Barbarians
Barbarians occupy City-States like other Tribes, but they are in a permanent state of War with all Nations. They have a number of special units: Marauders, Skirmishers, Elite Marauders and Elite Skirmishers.
Improvements
Improvements can be used to grand various bonuses to a City. There are two types of improvements: rural and urban.
Improvements without a Specialist will increase the City's Maintenance.
Rural improvements
Rural improvements may be built on any non-urban tile. Tiles where Rural improvements may be constructed will show the improvement with an icon above if a Worker is currently standing on the tile.
Urban improvements
Urban improvements expand the urban area of a city by transforming the terrain underneath to Urban.
