Hellblade: Senua’s Sacrifice had such a vivid portrayal of auditory and visual hallucinations and the psychological aspects thereof, as well as being rooted in genuinely spooky themes. Playing it in the dark with headphones was a truly psychologically scary experience and it didn’t really rely on jumpscares for the scary factor. ( which to me is a huge plus )
I thiiiink they’re modding the game but still playing on official hardware, so they might be in the clear for now (until Nintendo goes further)
