History YMMV / NineHoursNinePersonsNineDoors

* EnjoyTheStorySkipTheGame: The DS version is highly praised for taking advantage of the system's unique features in telling the game's story. The actual process of playing through each route on the DS version is tedious, however (especially compared to the remaster's quality-of-life changes), leading some to prefer watching a playthrough instead of playing through each route directly.

** The localization is mostly excellent, but its extensive use of similes comes off as inappropriate during certain moments, such as [[spoiler:Nijisaki / "Snake"'s death, which has his corpse compared to spaghetti and pizza dough. Justified, since this is the perspective of a child Akane who wouldn't know any other way to describe a corpse in that state.]]

* CompleteMonster: [[spoiler:[[BigBad Gentarō Hongō]], better known by his code name "Ace", first appears as a helpful and altruistic ally until he is revealed to be the [[CorruptCorporateExecutive CEO ]]of Cradle Pharmaceutical(s). He created the First Nonary Game, [[WouldHurtAChild kidnapping eighteen children]] and forcing them to [[DeadlyGame commit numerous tasks with their lives on the line]], for the sake of curing his prosopagnosia, inability to recognize faces. Hongō personally shoves the young Akane in an incinerator after an unsuccessful escape attempt where she burns alive, being too frightened and clueless to solve the Sudoku puzzle required to escape. In the Second Nonary Game, this time as a participant himself, he intends to betray and murder everyone in exchange for their bracelets, succeeding in the Submarine Ending. First, he successfully murders his three colleagues [[HeKnowsTooMuch in order to hide his identity]] and keep his crimes from never reaching the court. He also murders Clover in the alternate Safe Ending, later taunting her brother Snake how he loved the sensation. An utterly corrupted, delusional and sadistic man, Hongō is willing to murder anyone who stands in his way while at the same time trying to claim that he is a tragic individual.]]

* RetroactiveRecognition: Believe it or not, that's [[WebAnimation/HazbinHotel Alastor]] as the voice of [[Creator/EdwardBosco Seven]].

** The mostly [[PlayerPunch excruciating]] Safe ending also provides [[spoiler: one of the most inappropriate moments imaginable for a ''Franchise/MetalGear'' joke to make itself. I guess we can assume that "Snake! ''Snake! SNAAAAAKE!''" would sound better if we could actually hear Junpei's voice. (And we can if playing the remake.)]]

** ''999'' is also a case of '''First Version Wins'''. Several aspects of the game ([[spoiler:meaning the twist of the bottom screen narrator being Akane, as well as the final puzzle]]) simply lose the impact they had on the DS when played on the single screen of a console or PC. While the ''Nonary Games'' rerelease undeniably has some welcomed improvements (namely, the Flow chart), and is far more accessible, a lot of people will still recommend you play the original DS version of ''999'' first.

* AntiClimaxBoss: [[spoiler:Not a boss in the strictest sense, but for all the hyping up the last puzzle got, that was one easy Sudoku. Comparatively speaking, the replacement in [[UpdatedRerelease The Nonary Games]] feels much more climactic. Not that it's much harder - switch out some numbers then realize the password on the second screen is only one digit - but it ties into the game's arc a little better]].
