Ah Paulos… Age of Empires II: The Conquerers Expansion, are you covering Age of Empires II Age of Kings and Conquerers here?
Both rolled up in one, for I feel they are both pretty much involved in the same gameplay enough not to be specifically separate games. Example is that Diablo II Classic is a bit more different than Diablo II LoD due to the incredible improvements added by LoD, while Conqurer’s though adding new spices, it doesn’t add the BULK amount to be considered another game. But Paulos, it IS another game! Hardly, you need Age of Empires II: Age of Kings to install Conquerers.
