Trivia page for the Ace Attorney: Investigations subseries.
- Ascended Fanon: Gumshoe had been called 'Gummy' by the fandom for years before Kay uses it as a nickname for him in this game.
- Cowboy Be Bop At His Computer: This review
claims that "Many [cases] feature Edgeworth getting wrongly accused of a crime, and hence needing to set things straight", when in fact he only gets accused of a crime once in the entire game (at the beginning of the second case); rather, it's Edgeworth’s friends who get framed several times, requiring him to defend them in the process of cracking the case. - The Danza: In Japanese, Jacques Portsman's last name is Yūki, just like his voice actor's first name.
- Serendipity Writes the Plot:
- Edgeworth's flashback to the DL-6 incident in the fourth case of the first game is masked heavily and bordered by a "cloudy" filter (in addition to the series standard of merely putting flashbacks in black and white) to hide the fact that it is reused from the original GBA game (and thus has a 240 × 160 resolution with a 15 bit color depth on a 256 × 192 screen with 18 bit color depth) while Investigations is otherwise free of such sprite reuse (contrast Apollo Justice, where such reuse is very blatant when it occurs).
- This also explains why Gumshoe looks exactly the same except for his tan coat in the flashback case. Gumshoe was dressed that way in Trials and Tribulations during case 4, which takes place in the same relative era. Back then it was due to the inability to fit an entirely new sprite in the game for a character who already exists, so they just did it via Palette Swap. The DS has considerably more storage space for sprites, but Gumshoe still retains the same physical appearance because that's what he looked like as told by the third game.
- What Could Have Been:
- Concept art for Shi-Long Lang featured him shirtless, with the constellation of Orion scarred on his chest. Seems the director objected to the toplessness, even after a feather boa was added to cover the nipples.
- A trailer shows Kay appearing in Turnabout Airlines. Whether this means Kay would have first appeared earlier, or that Turnabout Airlines was originally a later case, is anybody's guess.
- Originally the concept of the game involved Ema Skye as the protagonist and the game would focus on forensics tactics. It would have actually had her doing investigations alongside Edgeworth during the original trilogy and alongside Klavier during Apollo Justice.
- Concept art sketches show that Quercus Alba's design went through a phase with him looking much more like a gnarly old tree.
- Before it was a detective simulator, other genres were also considered, such as a dating sim and a fighting game.
