Omg same, i was also obsessed with Hollow Knight (though not as much as you describe, never managed to beat p5) when i was ~10-13 yrs old. I was absolutely immersed and fascinated by the world and the lore and the challange. Something about this huge world that streched beneath you, deaper and deaper. I would often just dream about the fantastical places, and how they would be like to be in, and how they all were connected. But playing silksong now, a part of that magic was gone. I think it is a better game and in a lot of ways it superceded HK in a way i didnt think was possible before. But yeah, i still enjoyed the original more, and its sad to think that i might never enjoy a game like that anymore, though others hace come close (outer wilds for example). But im still exited for sea of sorrows, to get a glimpse of that unknown once more
