Franchise: Ace Attorney

When asked about the possibility of a crossover between the Danganronpa and Ace Attorney series, Danganronpa series creator Kazutaka Kodaka stated he would be willing to lend out series mascot Monokuma to Capcom, but if Spike Chunsoft were given use of Ace Attorney characters, "they'd end up murdering someone or something. If [I] had a chance to use those characters, [I'd] definitely want to kill 'em in Danganronpa, so ..."

One line frequently misattributed to the Ace Attorney series is "You are not a clown. You are the entire circus." This line originates from a 2019 tweet which was then edited over a screenshot of Miles Edgeworth as he appears in Phoenix Wright: Ace Attorney Trilogy. Further contributing to the confusion is that there is indeed a clown and a circus featured in the "Turnabout Big Top" case in Phoenix Wright: Ace Attorney - Justice for All, although Miles Edgeworth is not present during this case. Coincidentally, a line similar to the misattributed quote was featured in the 2015 game The Great Ace Attorney: Adventures during the fourth chapter "The Adventure of the Clouded Kokoro", where Barok van Zieks at one point states: "...My learned Nipponese friend is obviously in training to be a clown, the way he regales us with such witticisms. To your future career in the circus."

According to series localization director Janet Hsu, they do not have a set process for localizing the series' many puns, but instead it occurs to them naturally:

According to series creator Shu Takumi in a 2017 interview, Capcom executives issued two mandates affecting the writing of Apollo Justice: Ace Attorney. The first mandate was that the game had to include Phoenix Wright in the story, which went against his original idea for a soft reset of the series. The second mandate was to incorporate the Lay Judge system, a real-life judicial system, into the story, resulting in the creation of Spoiler:the MASON System game program and the trial run of a new Jurist System in the game's last case "Turnabout Succession". The motivation for the second mandate is believed to stem from real-life changes in the Japanese legal system happening at the time of the game's release. While Japan previously suspended an older jurist system in 1943, the National Diet gradually implemented a new lay judge system (裁判員, or "Saiban-in") from 2004 to 2009. This system, resembling more democratic systems in North American and European countries, calls upon six random common citizens to serve as inquisitorial judges alongside three professional judges. Together, they make up the judicial panel, who analyze and investigate evidence presented to them throughout the trial before ruling on guilt and sentencing. Reflecting this, Spoiler:the Jurist System seen at the end of Turnabout Succession is made up of six random jurors guided by Phoenix Wright, where the player from the sixth juror's perspective has to rule the defendant Guilty or Not Guilty.

Takumi revealed that as part of the game’s promotion, Capcom collaborated with the Japanese Ministry of Justice and gave a presentation about Apollo Justice: Ace Attorney at the ministry's head office, implying that the system's mandated inclusion in the game was political propaganda. Despite Capcom cooperating in the Japanese government's push for this new system and despite participation experiences being reported as positive and easy to understand, the reception to other aspects of the system were largely negative. Complaints included gradually more severe sentencing since its implementation, the risk of criminal penalties for lay judges publicly discussing confidential deliberation room details after trials come to an end, and most starkly, calling upon Japanese citizens to put aside time to participate in the system, who were more unwilling to do so. This decline in interest was attributed to the length of both lay judge trials and pre-trial proceedings increasing significantly over the next decade. Due to aging populations and people simply being unable to make these commitments, more citizens refused to serve or even show up to be vetted for serving, making it harder to fill out the jury. As a result of this reception, the Ace Attorney series has not used Spoiler:the MASON System and the Jurist System since, sticking with the series' traditional Initial Trial system in future games.

Hideo Kojima, best known as the creator of the Metal Gear series, is a fan of the Ace Attorney series and tried to recruit some of its developers to Konami after the release of Phoenix Wright: Ace Attorney, including Shu Takumi and Shinji Mikami.

In the English dub of the Ace Attorney anime, the character Furio Tigre is voiced by Sam Riegel, the English voice of series protagonist Phoenix Wright starting with his appearance in Ultimate Marvel vs. Capcom 3 (with the exception of Professor Layton vs. Phoenix Wright: Ace Attorney, where Phoenix was instead voiced by Trevor White). Based on a tweet from Kyle Phillips, the voice director for the dub, this appears to be intentional, as the case Tigre was involved in, "Recipe for Turnabout", involved him Spoiler:posing as Phoenix in a plot to frame Maggey Byrde for murder.

The first 3 games in this series were released on the GBA, only in Japan. When the first game was ported to the Nintendo DS, a new case was added. This case caused a continuity error in the second game, when the original last case of the first game was said to be Edgeworth's last case. This was corrected in Phoenix Wright: Ace Attorney Trilogy, which updated some of the lines of dialogue to fit the new case into the series timeline. Specifically:

• "(But after "that" case was over...)" became "(But a little after "that" case was over...)"
• "After that case, Edgeworth was in a peculiar state, and he got worse everyday." became "Edgeworth was never quite the same after that case, and then, with the case after that one..."
• "That was one year ago. It was right after you left to go back home." became "That was one year ago. It was a few months after you left to go back home."

In the Japanese versions of each game, Maya Fey's favorite food is ramen. However, this was changed to burgers in the US releases.

Phoenix Wright's Japanese surname, "Naruhodou" is a reference toward the Japanese expression "naruhodo", which roughly means "I see", "I understand" or "indeed".

Sega built a theme park attraction called the "Gyakuten Kenji in Joypolis" dedicated to the Gyakuten Kenji games. The attraction has each visitor investigate a crime scene and look for clues in 20 minutes, after which they then write their conclusions in their own organizers.

Shu Takumi, the creator of the Ace Attorney series, had always wanted to make a mystery game. He gained this opportunity when Capcom told him to get 7 inexperienced employees and "make whatever you want". His idea for a lawyer based game was frowned upon by the higher-ups, but tried to convince them that the game would be interesting with its "eccentric" characters.

For series localizer Janet Hsu, Miles Edgeworth is the most interesting character for them to localize, because of his overarching character development over the course of the series while still retaining the same personality at heart.

When asked what lawyer from the Ace Attorney series they would choose to defend them, Ace Attorney Investigations: Miles Edgeworth director Motohide Eshiro stated he would go for the young version of Mia Fey as seen in Phoenix Wright: Ace Attorney - Trials and Tribulations, while the former game's producer Takeshi Yamazaki was more uncertain as he perceived all the other lawyers as "a little shaky".

When asked about the possibility of a seventh mainline game, Apollo Justice: Ace Attorney Trilogy producer Kenichi Hashimoto stated that it would be difficult to make a game that could appeal to both fans and new players, but believed it was essential for it to retain the same kind of story, characters, puzzles, and pacing that made up the "indispensable" elements of the series. Separately, series producer Motohide Eshiro expressed a desire to include Franziska von Karma in a seventh game after being largely absent outside of the Ace Attorney Investigations games.

Many players and publications have claimed that the Ace Attorney series was written to be a critique, satire, or parody of the Japanese legal system. These arguments often compare the series' setting with cultural differences and criticized elements of it, including but not limited to: a statistical ~99% rate of conviction; the reliance on witness confessions to secure them; immediate assumptions that a suspect is guilty upon arrest; the lack of a jury; corruption and incompetency among the police, prosecutors and judges; and exaggerated verbal or physical abuse in courtroom proceedings.

However, creator Shu Takumi's statements tell a different story. While he planned out Ace Attorney as a mystery game, he and other developers became concerned that the legal setting applied to it might misinform players about how the Japanese legal system works, but they did not know anyone who studied law to ask for input (Takumi later stated that he was afraid to ask lawyers who had not played the series for their impressions of it). In the end, he insisted that realism was not the point of the game, but to recreate his perception of a tense courtroom atmosphere for a logic and reasoning-based mystery game.

At one point during development, he and a group of developers visited a small local courtroom and sat in on four criminal trials as a "team-building" exercise, with a murder trial as their last. Takumi recalled realizing just how relevant crime is to everyday life and that the courtroom's atmosphere was quiet, undramatic, and "almost homely", notably lacking gavels and the shouting of "Objection!" However, he intentionally did not change the tone of the game's courtroom to reflect this, and it remained based on his original, exaggerated expectations before the visit.

In the official Capcom 30th Anniversary Character Encyclopedia, Dick Gumshoe's weapon of choice is listed as "Good-Natured Incompetence".

In the French translations of the games, Detective Dick Gumshoe is named "Dick Tektiv", a pun on the word "detective".

According to series translator Janet Hsu, the games that make up the "Apollo Justice Trilogy" were grouped together as such because Apollo Justice had a more prominent ongoing character arc compared to Phoenix Wright, despite Apollo Justice's name being in the title of only one game outside of Japan. Hsu felt that this would have been less confusing to some if the games were instead released internationally with sequential numbers like the game's Japanese title, Gyakuten Saiban. Apollo Justice Ace Attorney Trilogy producer Kenichi Hashimoto believed that Apollo could still be the focus of future games, but acknowledged this was yet to be determined.

From 2009 to 2013, Capcom Japan collaborated with the all-female musical theater company Takarazuka Revue to produce three musicals based on the Ace Attorney series, the first time Takarazuka had ever collaborated with a game company. The first production, "Gyakuten Saiban: The Truth Reborn", sold out all tickets on its first day, and with the second musical ("Gyakuten Saiban 2: The Truth Reborn, Again...") drew a combined total attendance of over 50,000 people. According to series creator Shu Takumi, the musical's director Suzuki Kei cleared the first four Ace Attorney games seven times each before sitting down to write the script. Additionally, while he was not involved in the first musical's production, Takumi did contribute feedback midway through the second musical's production. The musicals were successful enough that it prompted the Revue to partner with Capcom again to produce a musical based on the Sengoku Basara series, and once more to produce "Dai Gyakuten Saiban: New Truth Reborn", a musical based on the The Great Ace Attorney spinoff games.

Maya Fey's Japanese given name, "Mayoi", means "true evening". When written in kana, "mayoi" means "hesitation" or "doubt". The name was apparently picked from a list of kanji that Shu Takumi liked. "Maya" was chosen as her english name because it closely resembles her Japanese name. The name Maya can either come from the Sanskrit for "illusion" or, similarly to her sister Mia's name, as a pet form of "Maria", which is itself the Latin equivalent of "Mary". "Mary" is originally from the Hebrew for "bitterness". This could be a reference to her sister's unpleasant death. Other possible meanings include: "rebelliousness" and "beloved-child".
