has there at least been some violence
Not with any result. We tried to take some potshots at his mysterious mind control guy, but he was an illusion or some shit so it didn't work. Nothing more fun than being held in place by a guy you can't influence in any way....
I don't think in-game violence is gonna solve this: you need real life violence. I foresee a hail of dice and the face of a disliked GM in your future.
The sad part is, I think the guy has potential. He seems to recognize good and bad GMing in other people, but he can't see the same traits in himself. He even left his old gaming group and struck into the world of GMing because he had a sudden revelation (after playing with a bunch of other groups) how badly his original GM was doing. This is after
years of gaming together. Yet now, he's repeating the same exact mistakes that drove him away.
I wonder... does a player inevitably become their first GM? Perhaps I need to give him The Talk. The one where you explain to a new GM the truth about a GM's role in the game. That the GM is not the most important person at the table, and that the game is about the GM sacrificing his own ego to create a world in which the
players are the main characters. I think he is GMing from the perspective of a player, and still thinks that the GM is God and Protagonist wrapped into one.
Not sure how he'll take that. >_>
