Text file: Units.txt, Building.txt, Wonder.txt, Tileimp.txt

How Used: Flag; add text CultureOnly and the Citystyle found in civilisation.txt

Game Function: CultureOnly restricts who can build units, buildss, wonders, and improvements. This is to make Civilisation culture group unique units (like Legions for Roman Citystyle civs). With this flag only Civilizations with that citystyle can build this unit. You can list multiple culture styles in order to exclude a civilization.

Mods Implemented: Civ3mod by E. Legions (Roman), Samurai (Asian), SSwordsman (anyone else)
