I think we have three options: First, a sort of monster of the week type game. This would be similar to pfs but doesn't have to be the same thing. Characters would be continuous and can either become DMPCs every so often or simply "not get hired" for every job. Second, a game where no one knows exactly where it's going. There's a single overarching story, but each player takes turns running it to where they think it's going. A version of this would be running a single Adventure Path and rotating. Third, running three separate games, each with a different DM. Each game would meet less often because of the other two and the demands of DMing would be less. Each game would move very slowly however. I think between these three options my preferences from most to least preferred would be 3, 2, 1, but I could be convinced to whichever if overruled (still hoping our savior DM will appear!)
