Number 1 and 2 were incredible....so was Age of Myths. You control all aspects of an empires, all within a 3rd person, 3d perspective. You control the labor forces of your town, which consists of mining, lumberjacking, farming, hunting, fishing, and maybe some others.
Your laborers can also construct various buildings that allow you in turn to create different unit types, unit bonuses, unit skills, and additional types of buildings. For instance, castles allow you to create elite types of units, garrison infanty, and fire vollies of arrows at attackers.
There are literally dozens of unit types from halberdiers, swordsmen, war elephants, horse cavalry, camel cavalry, missile units, seige weapons...all with upgrades available in certain buildings.
