Really good quote here from Guardian review:
"Bloodborne like its predecessors, will spill its secrets slowly, over months rather than days. Part of the appeal of Miyazakis games is this slow-release effect, whereby riddles are unpicked and shared by the community, rather than plainly laid out on the first day of release. It brings players together, where the fiction itself keeps them somewhat apart. Bloodborne is, by any measure, an extraordinary game, one that runs forcefully against the commercial tide, subverting perceived wisdom that contemporary games have to hold their players hands, or make their shape and rules explicit from the get-go."
