"rule playing" - haven't heard that in years, and frankly, I think this is really kinda silly.
But anyway, I think I've said my bit about why I don't like the metagaming rule. At the very least, I'd appreciate clarification on "outburst" and more documentation somewhere about the Star Army and other factions approach to civilian targets in wartime, and what they consider warcrimes, and if they follow the modern Western military principle of not obeying illegal orders.
And secondly, as i've said elsewhere: expecting GM's NPCs to not get questioned is kinda.. foolhardy? I dunno. I get that maybe I'm misreading this, but it really reads to me as if it's intended to stop that *too*. Some clarification would be nice. If there's a rule that basically is "At the staff's discretion, we can say something is too much", I'd like at least a hint as to where the line is.
