- Because it's a series with such a long history, it's hard writing stories and characters that don't overlap with previous titles in the series.
- In general, they first come up with the game mechanics and then the scenario and the characters to show off the mechanics.
- It had been the idea from the start of the project to include Maya. But then they also wanted to include forensics (and Ema) for the fans who wanted forensics back, and they needed the new setting for Phoenix, so they needed the Divination Seances and they also needed Apollo back in Japan.... so somehow AA6 somehow became the game where the whole series basically came together.
- The idea for Rayfa came from the fact they needed a priestress to do the seances. But that alone seemed a bit weak of a background for the heroine of the game, so they made her the princess too. Nayuta was always imagined as a Buddha-like prosecutor, who was overwhelmingly strong and could see through everything. They imagined him as a character who transcended even gender, so the design was made ambigeous.
- About half of the development was new to Ace Attorney. The core members of AA5 remained.
- The second theme of the game is 'succession'. Those being succeeded, and the successors are being represented by Nick and Apollo, who both have their own stories about that.
- Case 4 was something Eshiro wanted to do. It was hard to fit in terms of plot, but they managed it by changing the usual pace by making case 2 consist of one investigation and one trial part. Case 4 is somewhat similar to 3-3, as that it breaks up the main story a bit, but it also helps 'reset' the player between case 3 and 5.
- The DLC case is also (temporarily) free of charge because the series is celebrating its 15th birthday.
