This game is still one of my all time favorites. I was annoyed by a spoiler in the official Dark Souls 2 trailers and decided not to watch trailers of games I wanted to play therefore I went into Bloodborne completely blind. And I'm glad I did because what an experience it was!
I loved the scenery, loved the setting, and for the beginning of it I was thinking, this is cool, fast paced Dark Souls werewolf game, I'm way into it! And then halfway through it made a turn into eldritch horror and that moment when I realized that will always live on as one of my top gaming experiences.
I'd read a bunch of Lovecraft's stories and I really loved them but I wasn't really into the expanded mythos beyond that and so this was the first video game I had played with this kind of stuff. I loved every minute of it, even the Chalice dungeons which I think I'm in the minority there.
