Racial Resources would be a nice addition to this mod. Having access to more than one, perhaps hamlets, villages and towns have a chance of discovering extra ones of the civs' races.
civs could trade away the services, allowing access to a limited selection of unit types whose list expands the closer the civs are (vassals give the largest selection). These resources would also impact relations with other civs.
Dark Elves may like you enough to assist you but they won't be happy if you managed to also have other elven allies. Dwarves and Greenskins would be the same. Getting access to Chaos units would probably cause a war!
