Faction Buildings: All factions now have at least 1 faction building unique to them, many have more.

Universal buildings: Common to all, incl. a administrative burden building, civilian defense and other such.

Military recruitment buildings: All factions now have their own recruitment buildings, justified by their respective roster. For example not everyone will have a chariot building if they don't have enough chariots to merit a 3 lvl building structure.

Landmark: New landmark buildings all over the place, most are unique, however there are some, especially in Anatolia that may that may occur in several places. Those I've employed in part as story telling devices, to hopefully peak the gamers interest and also serve a gameplay purpose. To many the Bronze Age may be relatively unknown, so building a landmark to Tarhuntaradu will hopefully spark interest to go look for information on him. :) As a example.
