Square Enix plans on selling Final Fantasy Dimensions for $28.99 or $32.96 if you buy the chapters individually. Final Fantasy Dimensions came out in Japan last year for feature phones under the name Final Fantasy Legends where it was split into 13 chapters:
The Last Dragoon
Light Snatching Ranger
The Knight wandering through the Darkness
Sorrow of the Memoirist
The Dancer’s Battlefield
Revival of the Knight
Fate of the Shinobi
Decisive Battle! The Avalon Empire
Fate of the World
It looks like Square Enix compiled chapters in a different way for Final Fantasy Dimensions kind of like how Final Fantasy IV: The After Years bunched the three episodes into an ending chapter. Instead of releasing the game all at once, new chapters came out every few few months. Prologue was a freebie and other chapters cost between 315 yen ($4) and 525 yen ($6.67) a piece. There is no bundle pack to purchase all of the episodes as a complete game, so all together Final Fantasy Dimensions costs between 3,780 yen ($48) and 6,300 yen ($80). It’s *probably not* either of those prices since some chapters are 315 yen and 525 yen, but Square Enix doesn’t say how much each particular chapter costs. Maybe a numeric mean of 5,040 yen ($64), which also happens to be the price of DS games is fair estimate?
Update: Special thanks to Seán for finding this Livedoor blog that has prices of all the Final Fantasy Dimensions chapters. The feature phone version was 4,410 yen or $56.
