By now, most fans have seen the trailer for Lightning Returns: Final Fantasy XIII and are at least partly aware of the new game system that will involve a limited time of 13 days in which Lightning must save the world.
Because, well, people keep asking Final Fantasy XIII producer Yoshinori Kitase about it. And since he's a polite guy, he keeps answering those questions. Aw, that's nice of him!
Well it is if you live in the Kotaku time zone at least.
