Game I'd like to see: Warhammer 40K

Knowing the characters I play, it may be surprising I want this but...Warhammer 40K. I don't mind which system but I want to play a game in this universe (that I'm still very much learning about)/. Don't really know what else to put...

I've never played the 40k RPG, but am now wondering if Space Hulk can be adapted to pbp with multiple players...

Space Hulk is that space marine game, right?

Space Hulk is too much of a tabletop game to use for pbp imo.

Check out Dark Heresy or Rogue Trader. Those are fully fleshed out rpgs, and also incidentally share similarities with Warhammer Fantasy Roleplay.

or Death Watch, if you wanna play a Space Marine

Will do! I knew they existed but I haven't gotten around to reading any. I know only war also exists.
