The weirdest way to engage with fiction by far, in my opinion, is taking the "chronological order is strictly better always" approach to sprawling (video or tabletop) game settings and then insisting it's a good entry point. Like. You realize the creation myth of the world and the Ancient Precursor War lore aren't things people will care about unless they're already invested in the story, right?
Like I promise you, promise you, that someone whose first exposure to warhammer 40k lore is an infodump about the Old Ones and the Necrontyr is going to have a worse time than someone who just starts at page 1 of any given 40k core book, which says:
And!!!
As a bonus. This means that you're introduced to the Emperor with the important part, that he failed completely, and his empire is ass, before you get any of the Emperor glazing in the Horus Heresy.
