I hope for a mod that goes all meta on the game, adding a "game master" as an NPC in the game. By interacting with him in different ways he could manipulate stuff like what amount of XP stuff is worth. You could perhaps threaten him to increase certain types of XP, but if you fail at your intimidation he punishes you instead. And if you kill him nothing is worth XP or drops loot anymore (sine you killed the GM). Then you would haveto go on a long annoying quest to resurect the GM again.
