I have a basic plot figured out. Two GMs required for management, co-world construction, thread weaving, critique, emotional support, and reliability. That last one, I cannot stress enough, is absolutely important. You need to be middle-schoolers with no real-world responsibilities and super skills, or adults with a not so restricting job and decent writing skill. You will be setting an example for all future players. I guess this can also act as an interest check. How many people would actually like to see a gigantic world, great mythology, potential in the Titanic loads for deep and likable characters, all likely on a potential Ilium scale?
