Having received my ebay copy of Rogue Trader in the mail this past week I have been reading the rules and scouring for ideas for Dark Heresy. So far the things I will be using are as follows.
Death World planet of Origin.
Origins Paths.
Equipment (especially cyberbernetics)
Ork Freebooters.
Kroot Mercenaries.
Background setting (and possibly the adventures).
Character Sheet.
Warp Travel and Star Ships.
As for the rest of the book, I find the new Careers a bit dry (exceptions made for Explorator, Astropath) and I still believe the Navigator is better as an origin then as a career. I find the profit and acquisition system for equipment a bit unclear and unmanageable (at the moment) and havent really made up my mind about the new psker rules.
Anyone else?
