They want it all

Up until recently, you were so far from taking the throne, you never considered the possibility of sitting on it. Even when your father's advisors brings it up to you. Even when you get close to him/her and they bring it up. Then your siblings started dropping like flies. Left and right, until you were nearing the top.. All because (s)he wants it all. Everything is customizable from the gender and looks of the advisor, to the king's name, and the name of the kingdom. No World Info either.
