Long time stalker, first time poster. I've recently developed a curiosity for two-GM campaigns, and how they might work. Has anyone ever played or heard of a tabletop game with more than one GM simultaneously?
My search so far has been fruitless and frustrating, so perhaps some of the experts here may have heard of such a thing.
If you have, how did it operate? I imagine that both GMs would be leading different parties, and that while both parties are separate, they would nonetheless be acting in the same shared world, and would perhaps cross paths occasionally. That's just how I envision it, but I'm dying to know if there's already something like what I want out there.
