I've just got acquainted with Black Crusade, and find myself liking it a whole lot. But one question I keep asking myself, for any roleplaying game really, is what a full campaign looks like rather than just moment to moment gameplay. And with Black Crusade I can't come up with a good answer.
So making the default assumption of the game's narrative structure, let's say the PC's are trying to launch a Black Crusade on the Imperium. This needs all sorts of resources, and the Compact system seems to be a fairly elegant way of setting up the various goals needed to achieve this end. Fleets need to be raised, armies turned to the cause, weapons procured, agriworlds dominated to feed them all... The works. So my question is how this is handled from the perspective of narrative pacing.
In many games, taking over a planet is something it'd take an entire chronicle to do. But one planet doesn't make for much of a crusade. But on the other hand a game where every session takes place on a new world where the challenge of the week presents itself and is subsequently overcome so the planet can be overtaken by the warband leaves something to be desired. The Infamy / Corruption mechanic adds a whole new dimension to this, putting a timetable on each PC's playable life span. Can't dawdle around too long in any one place or become a Chaos Spawn, but make sure you stay long enough to achieve your goals or... Also become a Chaos Spawn.
So I'm looking for input. Thoughts. Comments. Ways other groups have handled this, or if my interpretation is entirely off point. How does one address the concerns of scope and pacing presented in Black Crusade?
