Close to a year after Dissidia: Final Fantasy made its debut in Japan, Square Enix repackaged the English version as Dissdia: Final Fantasy Universal Tuning. The updated release had balancing tweaks, arcade mode, and most notably English voice acting.
Dissidia 012[duodecim]: Final Fantasy won’t get that kind of re-release, Tetsuya Nomura said in an interview with Dengeki PlayStation, since the overseas version is being released almost simultaneously with the Japanese version.
Nomura also said there will not be a "next title." That doesn’t mean the team has given up on fighting games, though. Later in the interview, Nomura says he believes he has done everything he can with the combat base. After this game, the Dissidia series could remerge with a new form. Nomura says the staff has been working on 1 on 1 fighting games for several years and would like to work with a new genre.
Director Takahashi Mitsunori tells Dengeki the 12th story (the new storyline in Dissidia 012) is 15 hours long. Dissidia 012[duodecim] also includes the 13th story from the original Dissidia: Final Fantasy, which Mitsunori says has an extra 60 hours of playtime. Like Dissidia: Final Fantasy, there is a data install option which takes up to 800 MB. The install takes awhile so Mitsunori recommends taking a nap while the game is installing.
