"Easy and funny + ultimate old six" As a time-traveling prince, it's okay for me to grant you the title of king and create a vassal state, right? Is it okay to visit a brothel in my fiefdom? The gambling house lost money. Is it okay if I confiscate your gambling house? Okay, since there is no problem, why is there a problem if I have no money to rob wealthy businessmen and attack small neighboring countries?
