Just got this game yesterday and it's pretty amazing. It's part History Channel, part RTS. Every campaign mission comes with a video preamble discussing the history of the events you're recreating by playing, as well as having short documentaries about varying aspects of life in the age.

Gameplay is standard Age of Empires, which is always satisfying. I'm just a wee bit miffed at the degree to which the camera is zoomed in. It would be nice to zoom out just a little more.
