Your mistake is seeing the Emperor's most faithful as military hardware and zealots...
After seeing the phenomenal work 343 Industries has done with Halo 4, I couldn't help but wish Games Workshop tried harder to make their own super soldiers seem like the best/worst mankind had to offer in almost every way to the normal dudes instead of just crazy religious assholes with big guns and chainsaws. I don't mean make them heroic or some dumb shit like that, but just really push what it means to be a Space Marine or a member of another highly regarded/well known group in the eyes of a normal human who may or may not think highly of them. Some may think of them as heroes based of things they've seen or heard, some otherwise because of course a lot of the SMs and Sisters really are crazy religious assholes who pretty much are inhuman. The point is I'd like to see more dialogue from the normal people in the 40K universe about the universe's most iconic figures and what they feel, despite whether they're wrong or right. For the love of god, don't take any of this as me saying I want 40K to not be grimdark because that's definitely not the case.
Seriously, how amazing would it be to see something like this with a Warhammer 40k twist? [link]
