I am part of a group, we are going to be playing Fate Core. There are going to be 4 of us playing. We want to be able to rotate the role of Game Master.
We envision playing in an episodic format. Each session will be a single episode in the story. In this way, we can play a non-linear game where each session could be past, present, or future. Much like a TV-show, some stories will take multiple episodes to complete, some only a single episode. This gives us a lot of freedom, especially if a single player is unable to make the session, we can can always play without the full team.
We have not yet discussed the setting or theme of the game. I don't think it matters much in the scope of this question, but for arguments sake lets assume it is not something wildly exotic, or restrictive in any way to the normal flow of the game.
Now, the issue we are facing is that we would like to be able to rotate the role of the GM between episodes, or story-arcs. While that in and of itself is not a huge issue, my question is how do we manage the characters? I recently answered a similar question but now that I am facing the issue myself it would be great to get more input.
To clarify; the exact problem I believe we will have is character advancement. Fate has a very simple advancement system based on Milestones. However, if the role of GM is rotating around, when one group of characters advances, characters that were not in the game at the time will not get that advancement.
How do we solve this problem?
