I enjoy reading the lore because it's messy and deep and I can go down the rabbit holes. It reads like an ultra-serious parody that doesn't acknowledge how unhinged it is and I respect that. Never got into the game, the books, or anything else other than the wiki though lmao.
Also some of the fans ruin it. People get a little *too* into Warhammer 40k and make it their personality, but that's true of many things.
