According to unofficial sales numbers from Japan, Final Fantasy XIII has fallen down to number four on the sales list over there, after a very big million-plus release day and a record-breaking first week. But otaku take heart: even though sales of the game dropped over a million units in the second week, this wasn't unexpected. Final Fantasy games always tend to take a dip after the "day one purchase" audience gets their copies. The last iteration of the series took a 1.5 million unit hit in week two. But even with the lower sales, about 200,000 copies were traded for the appropriate cost in yen, which indicates Square Enix is likely still on track to meet or exceed its six million target worldwide. That's a lot of chocobos. [Via Kotaku]
