Out of the AOE's I have played this one is definitly the best (Not to mention the classiest one)
I have been a fan of Age of Empires since the first one was released and today I still enjoy playing Age of Empries 2: The Conquerors!
Age of Kings was the start of AOE 2 I enjoyed the campaigns very much (I love history and I also learned alot from AOE)
Considered in graphics I would say it's "o.k" (you can't blame it though)
The stories were the best (I mean it's fun going through Attila the Hun's campaign seeing what happend back then!
Overall this game is amazing and I would keep on playing this game even if I'm just a fossil
