Hey all. Long time Rogue Trader GM here, decided I wanted to give Dark Heresy a try.
So what would you consider to be the "must have" books for Dark Heresy. Core rulebook, obviously, but what beyond that?
And where is the best place to start in the modules? I know many of them are meant to be played sequentially, so where is the best place to start, and which ones are the most fun?
