Retired PlayStation exec reckons Bloodborne PC hasn't happened because Miyazaki 'cannot do it himself, but he doesn’t want anyone else to touch it'

Off the top of my head the workers in the mine had their scales removed which implied they were turning in to Crystal lizards, flame Lurkers controversy which was changed between the trailer and release, the fat boss with a bird in his head was changed but I can't remember what, maneaters and prison bell ringers were pretty significantly overhauled.

They are details which seem small and don't affect gameplay but affect the lore which Miyazaki clearly cares a lot about
