* ActorInspiredElement: Adrienne's jeans were not originally part of her costume. Her actress, Victoria Morsell, wore them in on the first day of filming and the producer decided they were perfect. Morsell states that, being already somewhat worn, they were held together by duct tape by the end of shooting.
* [[BannedInChina Banned In Australia]]: Regina's death caused it to be, although the rape scene, the other deaths and the violence more than likely also had a hand in it.
* [[CreatorsFavoriteEpisode Developer's Favorite Game]]: Roberta Williams's own favorite of her games.
* DevelopmentGag: During the installation of the game, a folder under the name "SCARY" is created, referencing the original title of the game, mentioned below.
* DevelopmentHell: The game took three years to make, the filming itself taking three months. Williams initially came up with the concept in 1992, under the name ''Scary Tales'', with a basic outline of what would be ''Phantasmagoria'''s plot, including a female protagonist, a magician and illusions. After researching some horror films and novels, she, along with Sierra art director Andy Hoyos, beefed the script to 253 pages.
* MultiDiscWork: The game is on seven [=CDs=], one for each chapter, with the Japanese UsefulNotes/SegaSaturn version having one more.
* NoExportForYou: The UsefulNotes/SegaSaturn port, released in Japan as ''Phantasm''.
* WhatCouldHaveBeen
** Poking around in the game's audio files reveals hints from the Hintkeeper (the skull in the HUD) during the final chase scene were recorded, but ultimately went unused due to the frantic nature of the scene.
** [[WordOfGod According to Ken Williams]], Roberta had filmed a scene that had Adrienne topless, exposing her bare breasts to the camera. Fearing the worst from the then-recently founded UsefulNotes/EntertainmentSoftwareRatingBoard, they had edited it down so you could only see a brief flash of sideboob.
