Civilization (Player Properties)
Determines which civilization the selected player is. Once a Civ is assigned to a player, that Civ cannot be assigned to another player, and cannot be chosen by the human player on the player setup screen.
NOTE: If a player ‘s Civilization is set to "Any", any available (unassigned) civilization may be selected for that player at the player setup screen. If the player’s Civilization is set to "Random", a random civilization will be assigned, and may not be changed by the player at the player setup screen.
