I missed Age of Empires II so much, more now that the third came out.
I think Ensemble tried to mix AoE II with Warcraft III (the greatest game of all time) without taking advantage of those games strenghts (AoE II's huge number of civilizations and Warcraft III's cinematics) and without offering a true RTS experience. And what's up with the home city ?? It's really a drag to be traveling back and forth to the home city to send "cards" to my town, I think it unbalances the game since you can actually win a skirmish game without building a barracks or a stable (you could call soldiers from home city and wait till you get the mighty fort to build more troops).
Overall I think the game improves a lot on the eye candy part but leaves out the substance from the previous game. The micromanagement is not really good on this game (where in hell do villagers put all the coin they gather ?? and why do plantations gather coin if they look like a more improved mill ?? Instead of a plantation we should have an underground mine or a metal workshop perhaps. So if all you like is a nonsense warfare (much like USA's wars against "terrorists" ) you'll love the game, but if you are interested in a more realistic civilization don't expect to much from this title.
I still recommend it even over Rome Total War (it's too slow paced for me) but it is very well under the Warcraft saga.
