There's a lot of nonsense involving alternate timelines and such, which I still think was fanon that Nintendo saw and went 'yeah, that'll work', but most of that can be ignored. Really, with Zelda games, unless it outright declares itself to be a sequel to a previous game, there's not much to worry about.Basic details that always apply. There's an ancient evil known as Ganon, out to conquer/destroy the the world. Two people are constantly reincarnated to smack him back down. Link, the guy with the magic sword, and Zelda, the Princess, who never gets to have the main role because bullshit reasons, but at least she's not 100% damsel in distress any more. Even if it's mostly offscreen, she gets to actually do shit now.
As for the Blood Moon, that's unique to Breath of the Wild. Personally, I'm not having too many problems with it, but then, I'm weird enough that weapon durability isn''t annoying me either, so make of that what you will.
