History Trivia / DissidiaFinalFantasyOperaOmnia

** Whenever abilities and/or any attacks are used successively on an enemy without any pauses between players'/members' decisions, the enemy target's pain animations when taking damage from BRV Attacks may fail to load properly and the models may just simply appear to stand still despite taking damage, even when there aren't any defensive/resistance modifiers applied to the said target.

* ModelDissonance: During certain animations, it can be easy to notice a model of someone wobble around a bit; this is heavily noticeable during certain abilities used to land a killing blow during a slow motion portion during a final wave of an encounter (Yda's Snap Punch, Noctis' Warp Strike, Yang's Kick, etc.).
** Likewise, there's also times where the models that are not properly aligned against a respective target will face at them via an awkward angle if player inputs are rushed through outside of the auto-battle function, as likely the game was interrupted in the process of properly orienting the character's model towards the target.

** Also applies to characters who only had voice actors in the ''Kingdom Hearts'' series, most prominently Selphie, Vivi, Seifer, Raijin and Fuujin.

** Outside of Zidane and Kuja retaining the long-time actors, this is the first time just about anyone from ''IX'' outside of Vivi has been voiced, and once again Square did not skimp on securing talent for some of the franchise's most beloved characters. Garnet landed none other than Creator/MamikoNoto as her voice, and Eiko gained rising star Creator/HisakoKanemoto as hers. Freya gained the voice of veteran actress [[https://en.wikipedia.org/wiki/Ai_Orikasa Ai Orikasa]] (best known to many as [[Anime/MobileSuitGundamWing Quatre]]). Steiner is, again, the only odd man out (being voiced by relative low-key character actor [[https://www.imdb.com/name/nm4893056/ Minoru Hirota]]). Beatrix was a particular surprise given that her Japanese voice was first revealed in the ''global'' version, and the world found out that Creator/YukaKomatsu had been recruited for it... and while previously she might've been a comparative unknown, she is now coming into this role screaming hot off of gaining ''international'' fame [[Anime/DragonBallSuper for her role as Caulifla in a certain globally-simulcast anime]].

* NoDubForYou: Surprisingly, the global release of the game retained Japanese voice acting for all characters, making ''Opera Omnia'' the first piece of ''FF'' media to not get an English dub. [[note]]The PSX and PSP versions of ''VideoGame/FinalFantasyII'' technically don't count, being limited to brief grunts.[[/note]]

*** Also inverted/averted for a lot of other characters, especially those who never either made a non-mainline series appearance (such as in ''Kingdom Hearts'' or ''World of Final Fantasy'') or a prior ''Dissidia'' appearance, as this game will be the first Japanese voice debut for a lot of upcoming characters.
