- An Imperial enemy with the level of plot armour of the Rebel Alliance has will drive your players bonkers.Unless the players ARE part of the Rebel Alliance… in which case, the Referee will have to work fast to keep things unexpected and interesting, instead of things shifting o the Boring Invincible Hero levels of Mary Suedom.
- Of greater interest is the Halo universe, where a hero (…or a small PC team…) has to carry ALL of the plot armour of the good guys. This can be good storytelling, if you can make their victory unpredictable. “Earn your happy ending!”
- As for anti-plot armour, on the scale of the prequel’s Old Republic vs the CIS… I would suggest that the Rebellion Era Imperium has a good dose of it, with an idiot, Emperor Lucan, rising to the throne at the critical moment.But it isn’t truly completely unexpected.Looking at the long history of the Third Imperium, I would suggest that the Imperium has a good helping of plot armour, simply to last 1,116 years with only one (not very destructive) civil war, and only one significant secession movement (the Solomani Movement).
Moreover: the Imperium certainly has some incompetent leadership from time to time, but only one incompetent really did damage (the last one, of course). And that last one was a matter of bad timing.
Had Lucan rose to the throne in more normal, peaceful times, things would have carried on much as before. More wild parties at Capital, more prompt executions for annoying military officers, and a greater push for Sylean cultural supremacy (as opposed to the Solomani/Vilani mix), but nothing the Imperium hasn’t easily survived before.
Lesson: “Plot armour for empires thins over time, getting more brittle. Gotta keep it thick and flexible!”
Addendum: Battlestar Galactica’s 12 Colonies has plot armour… just not enough of it.
The rest of you billions are just out of luck. Sorry.
