I just started to get into 40k, if you like reading, Dan Abnett’s First and Only is a good introduction to the world. It doesn’t expo dump you, and has a nice enough plot to follow.

Think also that it depends on whether the user gets the humor. Liberty Prime, the Imperium, etc. aren’t things to support what they stand for at face value, yet some do.

Like, I remember a while ago seeing a thread on reddit where some dude was saying that Fallout was a parody of communism, and not capitalism, and his argument boiled down to “when government does something bad, it’s communism”.
