I'd be interested in either Dark Heresy of Deathwatch. One issue I have with DW, as mentioned, is that it's heavily focused on combat. Ya, space marines are warrior monks, but the books is full of all these thoughts and play styles where you have to oversee some political negotiations or defending someone instead of just prosecuting everyone with your holy bolter. As an aside, I'd kind of be interested in playing in a single chapter game rather than members of the Deathwatch. This would open up a lot of tactical options while taking out a lot of the chapter emo that permeates the books. It would also open up more options for fighting daemons and other threats instead of just blowing away Tyranids. I'm fine with a more traditional game, but I see a lot of wasted potential with DW (FPS the game instead of an actual roleplaying game) Regarding DH, I can go any way with it. Although the game is tragically entertaining, I haven't really seen any play style problems.
