Why not two of same nation in game?

[Kristoffer O]

When we first made Dominions we didn't want multiple Versions of a nation in a single game. It kind of ruins the feeling. In a way, themes is a step away from this path, but we are still inclined not to allow mutliple Ulms. It would not feel right to conquer another Ulm containing yet another Keep of Ulm.

When moddability is implemented 'Civil wars' are most likely possible. For example: A war between Ulm proper, an alternative Ulm with the capital Black Forest without Black Knights but Rangers of the Black Forest instead and another alternative Ulm with the capital Staahldorf, no Guardians but Iron Guards.

As long as the changes are small it would not be too difficult to add several nations of similar abilities.
