CanadaEternal Darkness: Sanity's Requiem is the first game to be developed fully by a Canadian developer, inside Canada, and published by Nintendo Of Canada (NoC). As a result, it was released in Canada two days before the U.S.
DevelopmentEternal Darkness: Sanity's Requiem was originally planned to be one of the last games released for the N64. Once it slipped that release, it was scheduled to be a GameCube launch title and be shipped in October 2001. It didn't make that date and was once again rescheduled for release in February 2002. It still didn't make that date and was finally released in June 2002. Because it was in testing for so long, the in-house testers at Nintendo began calling it "Everlasting Darkness."
Fourth wallSilicon Knights co-developed the remake The Twin Snakes of Metal Gear Solid with Konami. Given that series' fondness for breaking the fourth wall, Silicon Knights reused some of the Eternal Darkness sanity effects, such as the tilting floor effect, during the player's battle with Psycho Mantis. Eternal Darkness is also one of the games recognised when the character attempts to "read the player's mind" (which consists of reading the contents of the system's memory card). Breaking the fourth wall in such a manner is a notable stylistic similarity between games developed by Silicon Knights and those developed by Hideo Kojima.
InaccuraciesIn the manual when describing Dr. Maximillian Roivas, they put the date and setting of "A.D. 1760 - Rhode Island, USA." Not only is it glaringly obvious that the United States not even exist at that point, but Rhode Island didn't even join the Union until 1790! Oops! The developers, Silicon Knights, are Canadian.
NamesAlexandra's family name, Roivas, is savior spelled backwards.
RatingsThis was the first Nintendo-published game ever to receive a 'Mature' rating.
- This game has several homages to classic horror and fiction writers. As if the Edgar Allen Poe quote on the intro wasn't enough, the guy who speaks to you on the beginning of the game introduces himself as Inspector Legrasse... and there is an Inspector Legrasse on H.P. Lovecraft's tale The Call of Cthulhu. The setting being on Rhode Island is another tip of the hat to Lovecraft's place of birth.
- Mantarok, the creature encountered by Ellia, is the keeper of "The Ancients". An obvious reference to Lovecraft's Yog-Sothoth, who is the keeper of The Great Old Ones. Also they both coexist in multiple planes of reality.
- While playing as Alex, check the stack of books in the study, to find another reference to classic horror tales, including Poe and Lovecraft.
- One of the sanity effects has the character's head falling off and quoting Shakespeare, more specifically Scene I, Act III of Hamlet, the famous "To Be Or Not To Be" speech.
References to the gameIn Metal Gear Solid: The Twin Snakes, magazines called ED Magazine can be used to distract guards. The magazines show Ellia on the cover and a centerfold of Alex Roivas when used, two characters from Eternal Darkness: Sanity's Requiem.
Title translationThe translation of the Japanese title in English is "Eternal Darkness: Call of 13 People".
