    First, I'd like to say that this game could have potential, but in its current state, entirely too complicated. You spend more time on building, troop, and resource management than actually warring. Too many buildings produce units. Too many buildings with unknown purposes. Different units build different things. A few suggestions to make gameplay smoother/easier: 1. Designate one type of unit that can build ALL the things. Not females can build these things and males can build other things. 2. Reduce the number of buildings that produce units. Barracks, cavalry, artillery, and maybe keep the civic center to produce civilian units/builders. 3. Create a single place to research new technologies, rather than every single building needing to be researched individually. These three basic things I believe would improve game play dramatically and reduce complexity. Usability wise, the whole, demo, campaign, skirmish, sandbox selection needs a complete overhaul. I have no idea if what I'm selecting is what I'm actually playing half the time. Set the game mode first, then only show maps for that game mode. Make it simpler/easier. No reason why selecting a map needs to be so complicated.
