I've noticed that when I take certain cities, certain buildings are labeled as "Infested", "Civilized", or "Barbaric". I understand that this basically means it was built by a different faction, but does it mean anything more than that? Is there any reason why I should consider destroying a building and replacing it with one of mine, or does it not really make a difference?
Any information would be greatly appreciated.
(I apologize if this information has already been posted somewhere and I just somehow missed it)
