Final Fantasy IV: The After Years

Originally designed for Japanese cell phones as Final Fantasy IV the After: Tsuki no Kikan, Final Fantasy IV: The After Years is a sequel that retreads every single plot point from the original game, except worse.

It was ported to WiiWare in painfully expensive episodic form, then given a high-res upgrade for the PSP as Final Fantasy IV Complete, featuring the original game and a brief, pointless bonus chapter linking the two called Final Fantasy IV -Interlude-.

Dummied-Out Items
All of the items in Final Fantasy IV Advance are implemented to some extent in this game, even if they aren't actually used in After Years. This includes all the bonus dungeon items, key items, equipment, and so on. There are also a few dummied-out items that were originally intended for this game.

 * Amulet of Memories: "A necklace packed with memories"
 * Bloody Spear: "A spear smeared with blood"
 * Crystal: "A crystal that gives off a holy light"

 * Ring of Memories: "A ring packed with memories"
 * Shiva Crystal: "An ice crystal handed down by Shiva."
 * Siren: "Automatically sends player into a battle."

Unused Weapons

 * Pig's Bamboo Sword: "Removed from this title" - 158 attack, +99% accuracy, inflicts Pig status, equippable by Cecil, Ceodore, Kain and Golbez. If the Developer's Room is any indication, pigs were kind of a in-joke among the developers. This is the Piggy's Stick from Final Fantasy IV Advance.

Unused Equipment
