Warhammer 40k lore is AMAZING. I love all of the stories I've read in it. Not only is the backstory cool science fiction, but the "current" period reads like a futuristic mixture of the pre-Enlightenment dark ages, and the Russian military in WW2 (surely not by accident). There are many great novels, but I love the human scale and protagonist in the Ciaphas Cain novels -- he's a cowardly "commissar", and it makes great humorous reading. Also, "Eternal Darkness: Sanity's Requiem" (gamecube) is almost explicitly Lovecraftian. It's amazing.
