Speaking with Yoichi Wada, the President and CEO of Square Enix, Siliconera unearthed Wada's easy explanation as to why Final Fantasy XIII went from being a PS3 exclusive, to a multiplatform title. According to Wada, Microsoft had been "asking" them to bring Final Fantasy to the Xbox 360.

"The Xbox team has been asking us to have a [Final Fantasy] game developed on our platform. Also, the Xbox 360 console is available in many homes in US and European markets so that was not really a hard decision to make," explained Wada.

The latter half of the answer sounds a tad understated compared to just being asked to make a game. It would be hard to believe Microsoft didn't offer to pitch in on the marketing front, but that's really nothing to do with it, right? Jokes aside, there you have it.
