The defining factor to discerning and understanding Bloodbornes story is binary.

Bloodborne dun fucked it up in the story department as far as I am concerned: I have not read the aforementioned novels, but I should not need to: Demon's Souls and Dark Souls presented an engaging story without any prior knowledge of anything, Bloodborne fails to do so for me.

I have finished the game, but doubt that I'll be returning to it upon - if, I ever read those works.

Except it's not about establishing a story, it's about understanding a genre.
