Amen brother. This is the way the game is meant to be played. People just don't understand how much joy youre sucking out of the game by using wiki, guides, etc. Even for basic info you are just degrading the experience. The game is bliss when you're scared shitless, you don't know where you are, you don't know what is around the next bend, you don't know if the next fog door is a boss or a new area. That sense of exploration and danger associated with it is something other games have never been able to provide. People think the game is just about survival, but the exploration aspect is the strongest part. Most people don't realize it because they get fed up with dying, or not know if there weapon is good, or they want to know how to get an armor set, etc.
Just play the game blind. If you get stuck on a boss, watch a video on youtube for strategy. Otherwise, just play blind. Yeah, you'll miss some items, you'll miss some areas, so what? You know how awesome it feels when you naturally find a secret area or a chest that takes a jump to get to? Its completely awesome.
I understand this is not for everybody, but you should really give it a chance. Replaying through the old content again for me wasn't even fun. Going through the DLC the first time not knowing anything was fucking amazing. Finding the secrets, overcoming the bosses with your own strategy, nothing comes close. The other great part is after beating it you look at all the guides and info and you realize you never found something, or missed an entire area. Then you get to redo it all differently on your next playthrough.
