I won't reiterate too many of the points already raised here.
This is such a cool location with some exciting internal logic. The z-fold format and two sided framework helps flesh out Tribune as a dynamic location. I think this premise and its major features are deserving of a larger zine.
The main concern I have is actually turning out a play scenario fitting the setting. The factions and their conflicts aren't as plainly laid out as they might be in a larger project format. As the OSR and NSR scenes often preach Situations Not Plots, the way these elements come into conflict could have used a little more focus.
The 'fighting fate' percentage roll feels almost too simple a system for what it determines, as it seems like a roll to see if this apocalypse can even be averted. I would have preferred that be rigid, or the space that mechanic takes up be used to expand the outcomes section to include the day phase colonists.
