So, there was an interesting moment last night. Despite the fact that I am, despite claims, a pretty nice guy normally I realized that I put on the mean 'tough guy' act when I GM. "Yeah, I'm not that nice" I said to a player when he asked why the proverbial shit was hitting the proverbial fan over the course of the session. Someone else, a friend who was watching then chimed in that I'm only nice to people right before I rip them a new one (he was talking about in games I run, and only that I hope). It all got me thinking.
Where did the idea of the Evil GM come from? What is it that started it off? Did it sprout from the days of old where GMs mockingly put notches in their GM screen for every player they killed? Or is that an off shoot of the evil GM as GMs played into the role, joking around with friends while pretending to be that quack of an adversarial GM who wanted nothing more than the players to feel utter despair at what their characters faced this time?
If that is an Evil GM, then what is a Good GM? Surely the concept of Good (the alignment, not skill level) GMing must exist if we have one for Evil GMing. But we never hear about the "Angelic GM" who runs awesome games, just the one that wishes you'd made a deal with the devil instead. So, where do you think it comes from? What do you think it means? Do you have any interesting stories to tell about being a truly diabolic GM? Or even of being an Angelic GM? What do the terms mean to you?
Please, discuss below.
