The series was created by Shu Takumi, who wrote and directed the first three games. The first game was conceived in 2000 when Takumi's boss at the time, Shinji Mikami, gave him six months to create any type of game he wanted to; Takumi had originally joined Capcom wanting to make mystery and adventure games, and felt that this was a big chance for him to make a mark as a creator. The game was designed to be simple, as Takumi wanted it to be easy enough for even his mother to play. It was originally going to be a detective game, with Phoenix being a private investigator, but at one point Takumi realized that finding and taking apart contradictions was not related to detective work, and felt that the main setting of the game should be courtrooms.
