Speaking with GameReactor, Final Fantasy producer Yoshinori Kitase has spoken of releasing a new game in the series every year to keep fans interested.
"[For] the current generation console[s], Final Fantasy XIII was obviously the first game, and personally I think we took a little too long getting it out," he said.
"When you think of Western AAA titles like Call of Duty, Battlefield, and Assassin's Creed, they seem to work with a lot shorter turnaround - they make a new game in one to two years. That is something we need to follow up, because that seems to be the best way to keep our fans interested and attracted to the franchise."
Final antasy 13, released in early 2010, was the first entry in the series for this generation of consoles. Final Fantasy 12 was launched in 2007 on the PlayStation 2.
Kitase admitted Square Enix "learnt a lesson" from the game's long development, and is happier with Final Fantasy XIII-2, which launches early next year after 18 months of development.
