The Improvement Mod touches on every aspect of the game, improving and tweaking every feature the game has to offer while also adding many new ones. The mod adds new units, buildings, maps, civilizations, soundtracks and game modes. All of this results in a very refined gameplay experience powered by an improved AI and more detailed graphics. Check the "Features" for more details. The mod works with both versions of the game, Steam and non-Steam, and is only available for The Asian Dynasties expansion but requires Age of Empires 3 plus The WarChiefs expansion and The Asian Dynasties 1.3. It is recommended to install over the AoE3 Complete Edition (Steam version) as it contains everything the mod needs.
Added the SweetFX graphical enhancer, which makes everything look a bit more colored, smoother and clearer.
Not bad for a game from 2004.
