Wait, isn't the plot centered around characters interacting with one another? Why would we need multiple GMs for that? Wouldn't most of the plot and events be made by the players?

From what I'd see, we'd have two different demographics filled with people with a diverse set of goals.  Sure, they'll intersect and intertwine, but it's hard to keep track of two different groups anyways.
