Have you ever found yourself playing a game that gives you an interactive storyline that lets you decide how your character responds to the NPCs? Have you ever tried to fool the system to see what happens even if you choose the obviously undesirable response? Chances are that they just ask you the same question again and again until you realize you're supposed to choose another option. While I admit Majora's Mask would have been a lot less fun if you decided not to embark on the Mask Salesman's quest, but still, I think it would be humorous if they allowed these options to play out.
