I can one up this. The obscured story told through items descriptions and vague dialogue feels like a meta game on its own for those who really want to venture in. To me it felt like I was rediscovering games again, reminded me of playing old games like Lands of Lore, Black Crypt or Ultima for the first time, strange sense of wonder. Never thought I’ll get this feeling again after so many years.
I'll one up you on that one: I kinda enjoy the Souls gameplay (in the most generic "I like winning" way) but it's everything around the gameplay what makes me want to play the games.
Then again, I do that for many things. Video games, tabletop games and even non-interactive media like comics, books, mangas. It's probably a faulty switch in my brain, but somehow I enjoy reading about and looking at the art of X (currently and fittingly to this thread, Berserk) more than consuming X.
