History YMMV / ShinMegamiTenseiIIINocturne

* HighOctaneNightmareFuel: The moment when the Young Boy drops the wriggling, bug-like Magatama [[EyeScream on your eye]] and it burrows into your brain? That'll do it.
** Even before that, the idea of the Conception itself. And that flash of light, followed by the Magatsuhi flowing out from buildings you see before Tokyo wraps itself up into a ball? That's '''humanity being wiped out in the blink of an eye without a fighting chance!'''
** Kabukicho Prison. Just...Kabukicho Prison. It's an abandoned building filled with empty rooms, some of which have voices from nowhere. And then the Mirage flips the building, turns everything white, except for the streaks of blood on the ceiling, and the giant, golden shutters. Behind most of those shutters are jail cells/torture chambers filled with Manikins.
** TheReveal as to the true identity of Hijiri.

** NewGamePlus: Much like Mara, if you have Legion (Comes with Tetrakarn), when he uses Andalucia, he will get hit by his own attacks. Just have enough Chakra drops to refill Legion's MP.

** On one hand, a Z-Class ApocalypseHow. On the other, an eternity of X-Class Apocalypses, one after another... until [[GodIsEvil God]] [[DespotismJustifiesTheMeans find that shining world]]... [[TheEvilsOfFreeWill the world with no free will]].

*** Taunt + Tetrakarn = Dead Mara

** And the Demifiend by extension, if he sides with Yosuga.

**** Heck, in this game, all the pre-boss musics bathes in pure awesome; we have [[http://www.youtube.com/watch?v=TzUmF3wRgJY&feature=related the theme that plays before a Fiend battle.]]It says: "You'll be fighting something ''horrifying''. Brace yourself". On the same vein, [[http://www.youtube.com/watch?v=fCoXfFOT-GI&feature=related this]] is the epic song that plays just before the True Final Boss. One of the most {{OhCrap}} inducing songs you'll find.

* DracoInLeatherPants: Lucifer and the "True Demon" demi-fiend get this a lot. The fact that their agenda involves destroying all life seems to be glossed over at '''best'''.

* ThatOneSidequest: The Labyrinth of Amala in its entirety. The mandatory parts put you through the wringer ''constantly'' and remind you it's particularly hard to assemble a powerful team capable of resisting continuous assaults (many back attacks, particularly) at the beginning. The optional Grave Run is also particularly tough, even with the endgame stats. Granted, the rewards are also proportional: reaching the end of the Fifth Kalpa before the Tower of Kagutsuchi nets you the sixth endinga and ''[[GameBreaker Pierce]]'', and the Grave Run gives you ''an extra Press Turn'' when you reach the First Kalpa's first Burial Chamber in a NewGamePlus.

** [[http://www.youtube.com/watch?v=5r1SKWfyGbc Tokyo Conception]]. Soft piano, for Yuko's lines... and then the booming organ pitches in, and the world '''''dies'''''.

** [[http://www.youtube.com/watch?v=Uct9il7pju8&feature=relmfu Metatron's Theme]]. There is no other song in the universe perfect enough to portay the feeling that you're practically giving God the finger at this point, and have inflicted his wrath. Bonus points for including a remix of the ShinMegamiTensei Law Theme.
