"This is exactly the sort of behavior you get when players stop role-playing. Metagame thinking is poison. I played this for a joke, but from my own experiences and from comments others have made I know this isn’t that far-fetched. I’m beating up on the players here, but you could make the case that stuff like this is the result of a DM who is strict about rules and lax about role-playing, which is about the surest form of self-sabotage a DM can do. If you adhere to the rules with meticulous authority and fill the world with generic NPCs, then soon enough you’ll have players treating your world like a place to mine treasure and farm experience, and not like a place where an epic story is taking place. The last thing you want is to end up DM’ing a game of Diablo." ~Shamus
