Summary: Gyakuten Saiban Official Fan Book 3 was released in 2007 coinciding with the release of Gyakuten Saiban 4 (Ace Attorney 4 - Apollo Justice), containing several pages on the development of the game. The longest article in the book is an interview with four members of the core development team of Gyakuten Saiban 4: the series supervisor and scenario writer of this game Takumi Shū, director Endō Mitsuru, producer Matsukawa Minae and planner Yamazaki Takeshi. The four discuss how the team structure changed for the development of this game, and the difficulties that arose from this transformation. Other topics discussed are about Takumi's drinking, things they'd argue about during development and changes made to the story. This interview is noteworthy for featuring director Endō Mitsuru, as he seldom appears in promotional material for this game.
