Possibly the worste RTS game ever
The gameplay is extremely slow and uninspiring. The units take forever to get to the other side of the map, and that's with all the upgrades. The Units are just disgusting to look at and very un-rounded. The Civilizations you get to choose from are all different, which is good, but they lack a little imagination.
The Graphics is super bad. Especially for the time that it was released. I mean, take a look at games like Command and Conquer. Beautiful and crisp. With EE3, you can literally see the landscape refreshing.
Campaign? What campaign? There is a world domination map that you can try and finish with all 3 your civs, that is if you can get yourself to play this bloody game. That's why I stopped.
Annoying Graphics, Units and Sounds just does not make this title worthy of its predecessors.
