It has quite a few magical and supernatural elements. Ug-Qoltoth (Ctulhthu) exists and you can fight his cultists and interact with his artifacts, Dogmeat is a supernatural creature, the game is intentionally noncommittal on whether the children of atom are right, you meet a ghost in the first game, there are psychics who can see the future and see events remotely, the tribe leader actually talks to the protagonist through their dreams in the second game, and lots of other things. Fallout has a pretty large amount of fantasy elements relative to games that are not outright fantasy like elder scrolls.
