A worthy expansion for a great game.
This expansion does bring a few new changes for example, you can now garrison foot soldiers inside battering rams, the mangonel doesn't fire upon enemy targets in the midst of friendly troops, also, some of the Age of Kings civilizations have been tweaked to make them more balanced with the rest.
As far as the single player campaign, four new campaigns (these detail some historical leaders like Atila the Hun or Montezuma) have been added.
Another great thing about this expansion is that the computer opponent's artificial intelligence has been enhanced, not only to make the game easier than for beginners, but also to make it more challenging for more advanced players
The Conquerors offers more additions and improvements, such as new map types for battles, as well as interesting new game types that emphasize production over combat.
All the additions in the Conquerors entice every player co concentrate on this great game for many years to come.
