Isn't Kings Landing supposed to say that you are the ruler of the five kingdoms, etc after you conquer it, get the message you are the ruler of the iron throne, and get the crown (my poor troops)? When you enter the town it just says what it would regularly say, not what it does when npc's capture it, you know ruler of the "everything". Just curious.
Interesting.
Just tried it, there is no mention of player being the king of the andals, protector of all the good stuff. Maybe it's a bug?
