There have been a total of four Ace Attorney games released for the DS so far and the upcoming title Ace Attorney Investigations, which stars the fan favorite persecutor Miles Edgeworth, will be the fifth installment to be released on the Nintendo DS.
Kotaku asked the developers whether or not they might bring the series to home consoles. “The games have always been sort of a portable game,” said Ace Attorney Investigations director Motohide Eshiro. “Even if we were to change the game and make it suitable for other systems, then perhaps the game would feel too far removed that people wouldn’t think it is an Ace Attorney game anymore.”
The series will eventually need to move somewhere once the DS life cycle ends, but until then it will remain “exclusively on the DS.“
