Final Fantasy XIII hit stores exclusively for the PlayStation 3 in Japan back in December 2009. That may now change though as an Xbox Achievements list for the game has surfaced on Japan's Xbox.com.

The news comes from XNEWS, probably Japan's largest Xbox information site. Interestingly enough, the majority of games that had their achievements lists leaked on XNEWS prior to an official statement were eventually released in Japan.

Final Fantasy XIII released in North America and Europe in March 2010 this year for both the PlayStation 3 and Xbox 360, however, the PS3 version managed to sell almost twice as many units than the 360. Considering the smaller 360 market in Japan, will releasing FFXIII on said platform be even worth the effort?
