Yeah, I won't have a lot of stuff to add, but I do have to admit that Warhammer 40K has some problems with ensuring that its universe remains credible. I get that it's a cautionary tale for our society which just happens to run mostly on a military-industrial complex, but it just seems to me like somewhere in there, there'd be humans advocating something else. A more rational approach, as opposed to the whole Emperor worship thing that's been going on for centuries on end. As things are, though, there isn't. Every human on Earth and throughout the colonies is hopelessly devoted to that one guy nobody's ever met, and individual thoughts are pretty much stamped out if they don't benefit the theocracy that's in place.
Look, Games Workshop. Yes, Dark Fantasy is cool. Very much so. It's cool that Space Marines pretty much have to rely on eldritch devices and hazardous magic to pass the light barrier and cross galaxies in a blink. It's cool that some side-effects might include getting swallowed up by Chtulhu expies or becoming indentured to Chaos itself. It's all very dark and grim. Yes.
But please, for the love of shit, don't give me that "In the future, there is only war" crap. When has there ever been "only" war as a culture's definition? Even our most war-mongering empires had their moving pieces of art or literature, even the Roman Empire at its most power-hungry had its playwrights, its philosophers and entertainers, even Vlad Tepes had paintings made. You can't just stamp out everything about Humanity except our tendency for blind aggression. It doesn't work that way.
While you're at it, GW, scrap the Ultramarines or just put them on the side for a couple years, huh? How about we focused on the more, say, human chapters? Granted, I'm not the most versed player out there, but I have played the other WH40K RTSes, and it did seem to me like the Blood Ravens could cool off if and when dropping blind zeal seemed to be viable. I'm not familiar with that many chapters, but I'm sure there's other teams, other groups, that just treat their service as a job, and not as a lifetime commitment.
I'm worrying about all this because as of now, the Warhammer 40 000 universe just seems like it's been designed to give an impression that's analogous to the one Gears of War tends to leave. Which is to say that in the future, you have guys that wear fridges for armour who are really, really INTENSE about fighting because LIFE IS WAAAAR, DUUR, and HOPE IS LOST and if we don't fight so hard even John Rambo starts to feel like a pansy, then WE'RE ALL GONNA DIE!
Sorry, Games Workshop fans, but I agree with Yahtzee. It just feels like thematic masturbation to me. They don't have to break apart the entire universe just to fix that, too. A couple human stories with human endeavours and stakes that aren't quite so desperate and things that aren't quite so bleak would go a heck of a long way towards fixing that. I'm not asking for the Emperor to get shot or for things to turn to sunshine and bunnies - just for a little something that's not quite as self-aggrandizing and complacent.
