To better reflect the character of the 12th-15th centuries, Age of Chivalry: Hegemony replaces or significantly alters each of the civilizations in the original game, adding many new units and technologies, allowing the player to control Central and Western European states.
The latest version of Age of Chivalry: Hegemony! Now includes a new AI, balance changes and gameplay changes, and a unique executable. For the full list of changes, see the readme included in the download. Comes with auto-installer and doesn't overwrite any files. Utilizes the Userpatch. If you do not have the C patch installed, you need to install it before installing Age of Chivalry: Hegemony (many new versions of AoK:TC come with the C patch pre-installed, in which case you shouldn't install it again!).
