I remember a good while ago things being discussed which related to civil wars & taking over leadership of an existing faction. I'd love to see formable nations too, like in games such as Crusader Kings, where if you meet a certain amount of requirements you could change your name etc to that pre-defined kingdom. Like imagine creating the warband kingdoms from Vlandia into Swadia (or even causing a large rebellion and splitting vlandia into Swadia & Rhodoks which would force settlement name changes etc)
