In our Dresden RPG we have a rotating GM seat. Each week a different player will be running the game. My session went so well they requested I run the following week. Which, alas, means I get no play time with my character.
So, in revenge, I’m working on a BDSM themed plotline to dump them into the middle of. Human cattle and furniture, total disrespect for humanity, body crafting and similar horrors.
And I want all of this to be the “good guy’s” lair. :p So the players have to work in concert with such an odious individual. And sit on his chairs ;)
