I think a new thread for that would be fine. It could get a little out of hand tracking who's where in each universe.
No new thread. There'll only be three players, as it is now, and as such only three universes will be tracked at any given time. I'll have a list of the universes in the OP, and the post just below that one will contain flavour spoilers for each one, such as PSAs, grafitti, worker handbooks, and personal letters. When an apocalypse is resolved, the universe will be 'completed', and will be moved out of the queue. The universe a new player will end up in is up to me, and its your job, as the player, to figure out whats going on and attempt to resolve the situation. Actions by the players are cumulative and the universe will continue to move linearly, but ONLY WHEN A PLAYER IS PLAYING IT. An apocalypse will be considered resolved when either a sanctuary is created (a new home world, a safe town for everybody, a space station where everyone can live), the antagonists are defeated, destroyed, or otherwise subdued (though it need not be permanent, they can be 'locked away for a thousand years' or somesuch), or the protagonist race is wiped out, enslaved, assimilated, etc. Multiple players can play in the same universe. Some universes may never be 'completed', and you don't necessarily need to strive to complete it.
