He's been taking the work of others in the Souls community almost wholesale without even mentioning them. That said, he's very good at making nice videos and soothing narration.
Wasnt that only a rumor for the bloodborne one? Where he started with the same quote from the lovecraft book as some other lore gatherer had in his document thingy?
Even if he was to steal content which i kind of doubt, it still doesnt matter, he makes great videos and has a great narrator voice and puts work into making the text sound like a story. It doesnt make sense to me if he does, but ofcourse all lore folks probably read what others have found, so finding similarities wouldnt be surprising.
