Basically feels like the original Age of Empires, just with the interaction of an online MMO. There are offline quests, as well as multiplayer, but throughout the game you're able to communicate with other players via the chat channels.
I've played the beginning few quests with the Greeks, definitely has that classic AoE feel. The co-op questing looks interesting, must try it out sometime.
Out of sheer boredom downloaded this last night. 50MB download. Almost 2GB worth of patches. There goes my 2GB Cell C cap...
So far I'm liking it, especially with the new type of "cartoony" graphics. I've always been an Age of Empires fan. First game I ever played on my very first PC was Age of Empires 2.
