Modifications
Age of Kings has some finished fan modifications and still some fans are developing new modifications for Age of Kings The Conquerors. Perhaps the most famous and most heavy modification is Age of Chivalry Hegemony. It changes all civilizations to medieval western European civilizations and adds new units, buildings and technologies. Because it is a total conversion, old units graphics are changed to new ones.
Another popular mod is the widescreen mod by boekabart which allows resolutions of 1920x1080 and higher.
Also there are modifications that do not edit the graphics, but add new objects to make the map editor more flexible and stronger. Renaissance made by Oliver adds more than 100 new units.
Currently work is under progress for a new mod called Forgotten Empires which will add five new civilizations to the game; the Incas, Indians, Slavs, Magyars and Italians. It will also add 29 new technologies and 14 new units, as well as other new features as yet to be announced. This mod is however still being tested in a closed beta, and is not yet available to the general public.
