Square Enix producers have more FF 13 stories
Despite the eventual existence of Final Fantasy Agito XIII and Final Fantasy Versus XIII, theres apparently still room for more "Fabula Nova Crystallis" games from Square Enix. Maybe.
In an interview in the Final Fantasy XIII Ultimania Omega guide, producer Yoshinori Kitase expressed an interest in continuing the Final Fantasy XIII story. "Id like to at some point make a story where Lightning ends up happy," director Motomu Toriyama said. Whether or not this becomes a game depends on demand from fans.
The team also revealed content that was planned as DLC but cut from Final Fantasy XIII: an area called "Seventh Ark" that would have offered "free battles." This was axed for quality reasons, as well as for differences in Xbox Live.
