Maybe I'm the weirdo here but I've never been someone who dives deep into ttrpg lore. Really I don't care that much about any "official" setting or what have you... Mostly I pick and choose whatever flavor catches my eye in a given book as a springboard to come up with my own ideas. It seems like so much more work to study and learn someone else's worldbuilding and setting details when I could instead spend that effort making my own thing with my friends...
As long as the setting supports the mechanics, you can really do and make whatever you want in a lot of games, and that's a huge part of the fun for me - following the prewritten stuff so closely just feels like an extra constraint that I really chafe against...
Idk. I've seen a couple big posts about how great it is to play a game with tons of prewritten lore and flavor that's deeply tied into the mechanics and character creation and whatnot and I've been trying to form my thoughts into something coherent. Not to say that stuff is bad or wrong ways to find enjoyment, just that it can also feel overly prescriptive and stifling. To me anyway.
I guess don't mind having this stuff as a starting point, but to me it's only good and productive if I can easily throw away whatever parts I don't care about and replace it with my own shit basically.
