Raises hand.Good grief, how could you possibly even begin to scratch the surface of that?
I'm a new DM. At least, I am compared to most of the rest of you guys (I've been DMing for about 6 years). 5e is the first and only TTRPG I've ever played, and when I started getting into the hobby, I tried to learn everything I could about D&D's main setting. So, I bought and read all of the 5e Forgotten Realms adventures and the SCAG, I read a lot of the Wiki, read the first 10ish Drizzt novels, and watched hundreds of hours worth of FR lore videos on Youtube.
I devoted hundreds of hours of my life to learn more as much as I could about the Forgotten Realms' lore as I could, and I barely scratched the surface. Eventually, I just gave up after realizing that I would never be able to learn it all and there were other settings that were way more user friendly than the Forgotten Realms.
And that's bad. It's a really bad thing to have your main setting be that ridiculously impossible to understand. I'm honestly baffled that the Forgotten Realms continues to be the core D&D setting. It's stupidly difficult to get into. Eberron is a piece of cake compared to the Forgotten Realms. Wildemount is 10 times easier than Eberron is.
Lore is fine. I like lore. Netheril is cool. Undermountain is cool. Chult and Icewind Dale are interesting adventuring locations, I guess. The Time of Troubles is an interesting idea, too. The Thousand Year War is awesome. Fantasy Gotham is nice. The fact that every god in the Forgotten Realms is just objectively evil is kind of a cool concept for a D&D world (even if this is just an unintended consequence of the Wall of the Faithless). There's quite a bit about the Forgotten Realms that I either sincerely enjoy or find intriguing. But all of it is buried under a deluge of endless information that it's nearly impossible to get to the good parts of the setting because you're getting links to articles about turnips or stuck in the convoluted metaplot about how Mystra died this week.
Sturgeon's Law means that not only is the vast majority of the lore going to be crap anyway, it will be harder to find the good bits of lore when there's a ton of lore because then there's more crap that you have to pick through.
