This mod adds variety to the game by adding 42 new city-states from a range of geographical locations and time periods. The ratio of militaristic to cultured to maritime city-states is the same as in vanilla. A number are intended as 'minor civilizations' rather than true city states, with a civilization name different than their city name (e.g. Buenos Aires for Argentina). Cities representing civilizations I think should be added in expansions/mods have also been skipped (e.g. Lisbon, Carthage). Civilopedia entries may be added in a later update, but probably not.

-Abu Dhabi
-Acoma
-Acre
