Playing D&D in the Warhammer 40,000 universe?

Yeah, you beat me to the punch. I do recall reading an article in White Dwarf (back when it was about RPG’s in general) about how little room the setting had for actual role playing, and what niches PC’s could occupy. But as I said above, by then I was more of a GDW and Steve Jackson Games player than a Games Workshop player. Except for Talisman. I still love the heck out of that game.
