My personal take on Sgt Rusk is that I brought him along because he's evidently deranged, and I was going to somehow try and heal his disordered mind through the Force.
As far as the rendering post RotJ EU non-canon goes, I'm not overly bothered; it's worth remembering that EU always was, according to GL, 2nd class canon next to the movies anyway(which also goes for the novelizations of the movies; they are interpretations of the source - the movies themselves).
Never forget, a wise man(or should that be wise guy?) once said "a great many of the truths we cling to depend greatly on our point of view".
Actually, none of a Space Marine's alterations would really save him from having a lightsaber jammed into him.
Just like any other organic, the water in his organs would flash boil(the lightsaber having a temperature roughly what you'd have experienced at ground zero in Hiroshima), so even though his blood would clot quickly, he'd still have been cooked.
You're ignoring the fact that those 6 movies are just one story - that of the rise, fall and redemption of Anakin Skywalker. That story has a happy ending.
LotR has something similar - the edning of the Fellowship isn't exactly all happy-clappy, and neither is that of the Two Towers.
It works fine in any group I've been in. The limiting factor is people staying to cream the last couple of enemies where they are instead of moving, not the format of the call.
You answered it yourself - IITS. Maybe, like Kazahkstan, one of the Seperatist worlds if the greatest exporter of potassium, and all other worlds have inferior potassium?
Odd. Back in the day, even the most advanced ships in 40k couldn't make the transition to warp space near a planetary body. IIRC, it took several weeks of sublight travel to go from orbitting an earth-sized planet to a safe jump point.
Knock bakcs are fun. Annoying when you're the one being booted into fire/acid/hole in the Voidstar. Bun fun as hell when you do it to someone else.
I like to yell 'FORE' when I do it.
Maybe replace it with a points system. Each win gets you 10 points, losing gets you 1. You need 30 for the daily quest.
And if you turn in 30 points of fail, then the game laughs at you.
