Medieval tradition also dictates that inheritance of positions is based on the blood links, which doesn't happen in BM which would suggest that BM doesn't follow that particular standard. The title Royal has a specific meaning in game, it relates to a character that has held the position of ruler. To RP otherwise to me is to attempt to have RP trump mechanics.
It's an adjective. Just a word. It would trumping game mechanics if he was trying to convince a Judge that it would be abusing a bug to ban the character. It's not abusing game mechanic to hate a realm because they tortured the little brother of their ruler.
