The mobile game Final Fantasy IV: The After Years, which is released in Japan, has been rumoured for release on Xbox Live Arcade after a suspicious empty page on the Japanese Xbox site, but an ESRB rating has confirmed the games presence on Nintendo Wii.
"FINAL FANTASY IV: The After Years
Platform: Wii
Rating: Everyone
Content descriptors: Alcohol Reference, Mild Fantasy Violence
Rating summary: This is a 2D role-playing game in which players embark on an adventure involving magical crystals and a mysterious kingdom. Players traverse across a field map or through dungeons and can enter into turn-based battles along the way. Players use a menu screen to select attacks or magic spells against tiny enemies (e.g., leopards, birds, knights, fish monsters, etc.) that blink and disappear when defeated. An item called "Bacchus Wine" is occasionally used to defeat enemies in battle."
It is unclear whether it will be a full retail release or a Wiiware title. A straight port of the mobile game seems more likely as a Wiiware title.
