* AscendedMeme: The idea of Archer having an Unlimited Food Works attack, given [[spoiler:his younger self]] loved to cook. In the Illya Castle minigame, he assaults his enemies with a hail of cooking utensils.
* AwesomeMusic: The opening theme [[https://www.youtube.com/watch?v=kIV-PvjXjSY "hollow"]]. The PS Vita remake's opening theme also counts, [[https://www.youtube.com/watch?v=UZWtIc0tays Hollow World]], sung entirely in SurprisinglyGoodEnglish by Aimer and the ''other'' opening's song [[http://chiasenhac.com/mp3/other/o-pop/broken-night~aimer~1427027.html Broken Night]], also sung by her.
* HarsherInHindsight: Caren's line "Stop? Or what, you'll violently rape me? That's a bit out of character for you, isn't it Shirou?" [[spoiler:Later on, Shirou -actually Angra Mainyu possessing/disguised as him- violently rapes Caren.]]
* HoYay: Issei and Shinji both have points where they are practically competing to see who is Shirou's best friend, at time actually fighting over him.
** While Rin is romantically attracted to Shirou, when her date with him at the pool is interrupted by Rider, Rin admits she and Shirou both noticed the same part of Rider's body. Rin goes on to note how beautiful Rider is and how she feels inadequate in comparison.
** While Caster avoids any of her DepravedBisexual moments from the original visual novel, she still expresses a desire to see Saber try on various outfits, this time only being played for laughs.
* {{Moe}}: [[EvilSorcerer Caster]] of all people manages to reach this status, sometimes reaching {{Tsundere}} status.
* SidetrackedByTheGoldSaucer: Assault Einzbern and the Hanafuda game can get quite addictive.
* TearJerker: During the opening, when a {{Brainwashed}} Shirou sees Saber again for the first time, he starts involuntarily crying with joy even though he can't remember why.
** ''The ending.'' [[spoiler:Angra Mainyu's final confrontation with Bazett, the reveal that ''he saved her life'' so she can return to the real world alive, their final parting and Angra Mainyu's HeroicSacrifice to end the cycle of four days, [[FaceDeathWithDignity calmly accepting]] that he must return to nothingness because [[BecomingTheMask taking on Shirou's form has made him also a "hero of justice".]]]]
** Both the backstory of Princess Medea, the Witch of Betrayal (aka. Caster) and the recounting of one possible route of the Holy Grail War (not one of the potential canon ones from the game) where Gilgamesh attacks the temple, mortally wounds Kuzuki, and leaves Caster to grieve over his dying form.
* TechnologyMarchesOn: {{Subverted}}. Several characters mention receiving an "anaconda of a fax" from Tohsaka containing the lengthy script of the SchoolPlay the archery club intends to perform for the [[SchoolFestival Cultural Festival]]. This may sound anachronistic for a story set in 2004, but it turns out that fax machines were still very much in use in Japan then and even ten years later for [[http://www.bbc.com/news/business-34667380 a variety of reasons.]]
* TheyWastedAPerfectlyGoodPlot: You might expect that now the Holy Grail War is over (and almost all the characters are inexplicably still alive) they'd take the time to explore [[spoiler:Archer's backstory, particularly what he went through to turn him from the idealistic Emiya Shirou to the cynical Archer, as well as how he's dealing with being back in ''his own'' past, seeing people he knew from his youth again]]. You might expect this. But apart from a single scene where [[ThoseTwoGuys Those Three Girls]] mention that [[spoiler:Archer]] seems strangely familiar for some reason, you'd be completely wrong and [[spoiler:Shirou and Archer]] just continue with their usual offhandedly antagonistic relationship. [[spoiler:This is because, at the time, the Archer Spoiler™ was considered one of the truly great sacred cows of the franchise and every single effort was taken to conceal it for people who hadn't seen TheReveal in the original game. Yes, even the fandisc sequel still tries to hide it. ''VideoGame/FateExtra'' took similar steps to conceal it. Nowadays, with VideoGame/FateGrandOrder casually spoiling it, it looks especially silly.]]
