I was wondering if there was any negative effects to a knight becoming rogue and maintaining that status for a prolonged period of time other than the obvious financial implications.
If not, perhaps there should be, say every week the knight loses 2 points of honor and 1 point of prestige, until a point when the figures reach X and Y when the night becomes un-recognisable as nobility and joins the adventurer game.
I think there should be some function for downward mobility and this would be a way of doing this. You could also end up with the situation that you could develop a whole new set of roles for adventurer infiltrators (assassins) adventurer-traders (smugglers) adventurer-diplomats (spies) adventurer cavaliers (horsemen - could have improved movement) adventurer heroes (could perhaps have a rally function to rally peasants against full rogue attacks or something). It could really add interest to the adventurer game and make them a more viable class within a realm.
It would also strengthen the rulers power to exile nobles, they become rogue and gradually lose face themselves unless they leave, just as the ruler loses face when they do not.
I just think it is unrealistic to think that a noble is always a noble regardless of their activities or lack thereof.
Just a thought
