Square Enix's Yoshi Kitase mentioned at Gamescom that DLC is being considered for future Final Fantasy titles.
As well as considering new items and areas in the latest main-line game, Final Fantasy XIII, Kitase mentioned plans to possibly make DLC a requirement in newer games, mainly due to the popuality of downloadable extras in the West.
As far as DLC is concerned, there is no solid plan at the moment for FFXIII. However, we've been listening to overseas fans in Europe and America and are aware that DLC is very popular and something that people really want. So it's definitely being considered for future projects.
Thanks to QJ.net for the tip.
Do you think games like Final Fantasy need DLC? If so, what sorts of downloadables would you like to see?
