Does the kingdoms one expand the area you can conquer in north and south americas or is it the map the same as from the original medieval 2?
The Kingdoms expansion provide 4 additional campaigns that are played independently of the original. One in the Americas, one tutonic (tutonic order, polish, etc.), one for the crusades and one in Britannia. All have there own factions and units that are different from the vanilla campaign. They are all quite fun, many say (including me) that it is one of the better expansions for a TW title.
