How about having choices for players in the campaigns for which objectives to pursue? E.g High elves could choose 'Keep all elves alive' (current elven campaign objectives) or else 'Disown Sirucil' (still has to keep Aevinwode alive, but doesnt need to help Sirucil and can even can go to war with or even destroy Sirucil for its decision to try to kill all humans).

That way each kingdom's campaign would be worth playing at least twice, choosing a different option the second time
