Theatrhythm Final Fantasy: Curtain Call producer Ichiro Hazama recently spoke to Polygon, and mentioned that more tracks could be added as download content from future Final Fantasy titles, meaning an almost limitless amount of tracks.
Hazama said:
"We wanted to make it so Curtain Call is like your base, and then you would add more songs as newer titles joined the roster and be able to accommodate for DLC or things like that and build upon it. But that would be our final form of Theatrhythm that handles the Final Fantasy songs. In terms of Final Fantasy songs, we will continue to produce new Final Fantasy titles and with that, there'll be new songs added to the repertoire."
Square Enix's rhythm game also got a large batch of new DLC tracks and another downloadable character in the form of Krile Mayer Baldesion from FFV. As well as five additional tracks from various Final Fantasy titles, four new songs from the Romancing SaGa series were added, in celebration of its 25th anniversary. Each track and character is available for 150 yen.
Romancing SaGa — Battle! Saruin (BMS)
Romancing SaGa — Sewer (FMS)
Romancing SaGa 2 — Seven Heroes' Battle (BMS)
Romancing SaGa 3 — Four Noble Demons 1 (BMS)
FFVIIAC — Advent: One-Winged Angel (BMS)
Last Order FFVII — Last Order (BMS)
