Producer wanted to make Theatrhythm Final Fantasy for the DS
You might be interested to hear that the concept for Theatrhythm Final Fantasy came well before the creation of the 3DS.
Producer Ichiro Hazama revealed in a new Japanese Iwata Asks interview that he had hoped to make the game for the DS following the completion of Final Fantasy VII Advent Children. The system’s lack of power and storage limitations prevented Hazama from beginning development, however.
And that’s where the 3DS came in. Hazama knew that the handheld would be able bring his ideas to fruition. Once Hazama saw the 3DS, he quickly met up with Indies Zero, the studio behind the title, to finalize plans. Tetsuya Nomura approved of the project and the team was able to begin development on the same day.
