Ah finally, a Warhammer 40K RPG that's set entirely within Imperial domains. It's a shame the d100 system is so clunky otherwise I'd be well up for that. There's enough intrigue, adventure and richness within the Imperium to carry a campaign, I think, without bringing in the armies of xenos and heretics. At that point you're better off playing the wargame (if you can afford it
).
