Maybe it's because I was a young child when The Legend of Zelda: Majora's Mask released in 2000, but I've always remembered it as the Zelda game that came closest to being a full-fledged horror game. Wait, no, it's definitely just because it's scary as hell.
Aside from the obvious stuff like the rage-filled moon that's staring at you with bared teeth, the whole game just has this pervasive sense of strangeness that's just really uncanny and unsettling. A few years later, Twilight Princess would inherit some of that spooky DNA, but that game is more analogous to a rebellious but good-natured teenager who hung around Hot Topic too much around 2006.
