alt Hacker News> It was more than just a joke. It was a satire on England and 1980's society.
Well... while I buy that to some extent, I think the point is oversold. While there are absolutely satirical aspects to the early game[1], they're mostly limited to puns. What (original) 40k is absolutely not is subtle highbrow comedy. It's a bunch of drunk nerds guffawing about whatever they thought was funny in the moment.
[1] Which again, didn't actually include a lot of the later lore. Like, the emperor in the 1e rules was entombed but strongly implied to be actively leading the empire. Likewise the original conception seems a lot closer to dystopian sci fi than "1980's society" to me.
It's dystopian sci-fi based on England though. The later lore is irrelevant, that's when it started turning into crap, especially around the later 2000s.
Here's the original from 1987's Rogue Trader:
""It is the 41st Millennium. For more than a hundred centuries The Emperor has sat immobile on the Golden Throne of Earth. He is the Master of Mankind by the will of the gods, and master of a million worlds by the might of his inexhaustible armies. He is a rotting carcass writhing invisibly with power from the Dark Age of Technology. He is the Carrion Lord of the vast Imperium of Man for whom a thousand souls are sacrificed every day, so that he may never truly die."
Definitely a Jesus figure. And a pretty subtly done one.
