The download file below provides you some add-on leaderhead graphics for the GEM mod. It wouldn't change any game play aspects of GEM. http://forums.civfanatics.com/downloads.php?do=file&id=10829 To use it, simply download and extract it to the "Giant Earth Map" folder. WARNING: If you are a newbie, backup your GEM folder first! For more advanced user, you can easily merge the add-on files manually with GEM. There is a single folder (Assets\Art\Leaderheads) and a standalone file (Assets\XML\Art\CIV4ArtDefines_Leaderhead.xml) contained within this download. Only the standalone will override an existing file in GEM. In order for you to reverse the action, I advise you to change the name of the original file. Acknowledgment: All of the graphics and text descriptions in this add-on file came from "Road to War" and CivGold" mods.
