 After the first game 's development was finished , <unk> told Takumi that they should make an Ace Attorney trilogy , with a grand finale in the third game 's last case . Takumi had originally planned to let Edgeworth be the prosecutor in all episodes in the second game , but during the production the development team learned that the character had become popular . This led to Takumi feeling that he had to use the character more carefully and <unk> ; he created the new prosecutor character <unk> von <unk> , to save Edgeworth for the game 's last case , and avoid a situation where he – a supposed <unk> – loses every case . As Takumi wanted the three first Ace Attorney games to be parts of a larger work , he avoided making a lot of changes between games : art from the first game for main characters such as Phoenix , Maya and Edgeworth was reused , to avoid having the previous games look outdated in comparison to newer games in the series ; and no new gameplay mechanics were added for Trials and Tribulations , as Takumi was happy with the gameplay after having added the psyche @-@ lock mechanic for Justice for All .
