In the past, I played in chat game RPGs, with perhaps a dozen or so GM's and maybe a hundred or more players. Together a living, interconnected game world was built. Has anyone done such a thing on roll20? I see some games, like the PFS with one-shots, but they don't seem to be focused on telling an interconnected story built by the player's actions. Has anyone out there run a multi-GM game on roll20 that are not 1-shots? Any success?
