Changes: It isn't a complete re-skin, I mainly made the armor a more realistic tone of that materials true color. e.g. The Copper armor is actually copper colored, and the Bronze has a reddish brown tone instead of being an odd silver color. I also increased the iron tone to be gold plated. The Destroyers armor was lightened to make the unit stand out more, the Lampades looks like a Halloween monster, and the Automaton is rather rusted looking or made from a bronze metal, or was dyed brown and the paint wore off. The screenshot which is unfortunately messed up is included in the folder, if you don't like what ya see just delete.
Version: Age of Mythology the Titans
Online: As far as I tested it worked fine online, it's just a skin change so there isn't much altered.
