Many people understood halfway through the game that the Bloodborne curse was a Cthulhu myth.
As a game of the same type as Dark Souls, the innovations in the combat system and level design of Bloodborne curse were not the biggest highlights of the game. If there had to be a highlight, it was probably that the game encouraged players to attack more, which made the game more "reckless", and thus created a more radical combat style than Dark Souls.
The biggest highlight of the Bloodborne curse was its unique world structure, which was inspired by the Cthulhu mythological system.
In fact, the bloodline curse was indeed regarded as one of the best Cthulhu mythology-themed games.
Then, what was the Cthulhu myth?
In short, Cthulhu mythology represented an 'indescribable fear of the unknown'.
However, this fear was not static. It was a very complete and progressive experience with a cause, process, and result.
