These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: Ace Attorney Investigations: Miles Edgeworth
Base Breaker: Kay, particularly among those who like the first three games best.
Complete Monster: Big BadQuercus Alba is the head of a large smuggling ring. The other criminals of the game (except Lance) ''answer'' to this guy. He is the one who ordered the deaths of Cece Yew and Byrne Faraday and killed Mask*DeMasque II and Manny Coachen with his own hands (well, with a statue and a knife, but you know what I mean). His reasons for these killings are as follows: Cece Yew was a witness who needed to be silenced, Byrne Faraday was a member of the Yatagarasu whose goal it was to expose his operation, DeMasque II was going to steal his fake statue and, with it, some plates used for a large-scale counterfeiting operation, and Manny Coachen because he ordered DeMasque II to steal it. Manny ordered the theft because he was planning to betray and usurp Alba and was unaware that the fake statue had been switched with the real one.
Disappointing Last Level: Compared to the other games in series, the final case is unusually long. It has far more chapters than any other case in the series. Just when you think it's finally over, it's not. Some fans have even criticized the finale for dragging out too long, and making the ending more tedious than satisfying, compared to the other games which arguably all had huge final boss takedowns.
Ending Fatigue: While you have to give the Big Bad of Investigations credit for being so tenacious, two full gameplay segments devoted just to cross-examining Albais too goddamn long.
The entire last case can be considered to fall into this (it is the game's ending, after all). As Edgeworth himself says halfway through the case,
Edgeworth: It's almost enough to make one completely mentally exhausted.
Ensemble Dark Horse: For someone who appears alive in only one case in Investigations 2, Horace Knightley is popular with the fans. Mostly because of his relationship with the Big Bad. Funnily enough, his Japanese name contains the kanji for 'horse'.
Escapist Character: Kay Faraday is what many Edgeworth fan girls dream of being. She's a cute 'modern-day Robin Hood' and gets to play assistant to Edgey, who feels a deep connection to her because of the parallels between her father's death and his. She's also Gumshoe's very best friend.
Even Better Sequel: Gyakuten Kenji 2 aimed to be bigger and more dramatic than the original, evident by the "final case" feel that the first case of the game was shooting for.
Harsher in Hindsight: Many people considered the reveal in the Apollo Justice game that Ema failed her exam and thus didn't achieve her dream quite harsh. With that knowledge, play case 3, where she appears as the same highly ambitious Genki Girl she was in the first game.
in 2, People cutting off Sebastian mid-sentence, clearing their throats to make him stop talking, having his testimonies called stupid by Gumshoe and Larry, and Franziska whipping Sebastian for being stupid gets much less humorous after the end of case 4 where his own father berates him in front of everyone else that everything he brags on about was actually thanks to Blaise's influence and nepotism, and that he's too stupid to be his son for not even realizing it and a shame to his dad. Even after that, just a mere few minutes later he was kidnapped and woke up in his own garage, leading him to think that his dad's men kidnapped him on purpose and really does hate him.
Sebastian: You don't understand, Mr. Edgeworth! I lost everything I had this morning! *cue 5 Logic Chess pieces*
Ho Yay: Gumshoe declaring that he'll show Edgeworth how much a man he is, and Edgeworth responds by asking if he should prepare a 21 gun salute now or later.
Internet Backdraft: The sequel not being released in the West due to the first Ace Attorney Investigations selling poorly. Fans are still clamoring for it to come stateside.
Karma Houdini: The sequel gives us Justine, who deliberately hinders investigations, rushes to convict the innocent while in an unofficial capacity, covers up the truth, and is generally just a gigantic bitch to Edgeworth. Sure, Blaise is coercing her on the fifth case, but she doesn't have any reason on the other cases, and the threats she made were all on her own, and in the end, she receives no comeuppance for her illegal actions.
Most Annoying Sound: Quercus Alba and Calisto Yew's Objections are both particularly annoying, as Alba's is really low and demonic whilst Calisto's sounds just whiny and weak. Not to mention the sheer lack of any personality or interest in the latter's voice. Portsman's coat swoosh also falls into this for some.
Player Punch: The second game has several. First, in Case 3, having to confront von Karma over evidence forgery as Gregory can count as one to players who know what it will lead to, similarly to being forced to present forged evidence as Phoenix in AJ. Case 4 begins with what looks like an attempted murder of Kay, her showing up heavily injured with amnesia... and then being accused of murder. And finally, in Case 5, finding out the real killer is Simon Keyes, someone who not only had Edgewoth's complete trust before, but who Kay considered a genuine friend. The moments before the big reveal are especially heartbreaking, with both Kay and Regina practically begging Edgeworth to prove it isn't true, and even Edgeworth himself being reluctant to believe it.
Rescued from the Scrappy Heap: Franziska, particularly in the second game. The first game has her very concerned for Larry's son (although it turns out to be a doll), and extremely sympathetic and even downright kind to Kay after she loses her father. In the second game, she's very sympathetic to Sebastian once he realizes how awful his father is. When Edgeworth gives up his badge, she still allows him to share his thoughts.
Franziska: However...once must be able to accept their father's mistakes, no matter how much they live up to him.
In AAI2, it's the Logic Chess battle against Sebastian. It's the longest and most annoying Logic Chess battle in the game.
Bansai's in the previous chapter is almost as bad, it's long and requires several actions you never needed to do before (such as going back on previous lines of questioning only to find options that weren't there before) and has to be ended by selecting the one option that penalised you every other time you tried it. Fittingly both battles are the only two in the game to use the "Allegro" version of the Logic Chess theme, and are family members.
To a lesser extent, Lotta Hart's during the fourth case. The battle itself isn't that hard, but the clock runs down at a far faster rate than in any other Logic Chess battle in the game, meaning that any mistake ends up being much more damaging.
They Wasted a Perfectly Good Plot: Though it feels unfair to bring up any aspect of the end of the sequel's fifth case as this, the Big Bad raises a particularly interesting legal question: can (or should) a chessmaster be held accountable for murders that he has deliberately manipulated other people into committing if there is no direct incitement to kill or other (provable) criminal activity on his part? Unfortunately, rather than answer that question, Jumping Off the Slippery Slope occurs when it turns out he actually did kill one of the victims himself and the case reverts to the traditional task of finding scant pieces of evidence that prove wrongdoing.
The Untwist: Blaise being evil in the second game doesn't come as much of a surprise, condidering their appearence and the fact their attempt at being Faux Affably Evil only make them come off as downright creepy. And the fact the only other suspect in the case is Kay Faraday. Of course, the real twist is just how evil they turns out to be, and the game's actual Big Bad is much more well hidden.
Although one could argue that there was still the stuff that he did in the past that makes up much of the final case's intrigue. Knowing the role he played in the SS-5 Incident really throws the curtain back on the amount of influence he has even into the present day. After all, his tactics and methods are the reason the Big Bad is who he is.
