I liked this one, as that is what happened.
This was also helpful, since I remember from the MS version of Age of Empires, which I had long since forgotten about.
One thing that has really slowed me down, is which building is which? I know that you can click on the building to "activate" it which identifies the building, but having a hover label on a building would be helpful. Yes, the building look different, but as of yet, have not developed that sensitivity to the visual cues. Would be nice to have building labels pop-up when the mouse hovers over it.
