[quote=@catchamber]If your thread was Closed, nobody would be able to crash land a spaceship into your plot without your consent, and you'd effectively be the Game Master for that specific iteration. However, if somebody made their own thread that basically duplicated your plot up to a certain point, and it diverged from yours with the hypothetical spaceship crash landing, other players would be able to take part in that story without interfering with your plot.[/quote]

Doesn't this essentially undermine the point of it being a Persistent World?
