Japanese game studios, Square Enix included, generally don't like cameras poking around where they make games. There are obvious reasons for that, such as designs or game info leaking out. Another reason is that, you know, people are trying to work!
Still, Square Enix allowed its own cameras into a Lightning Returns: Final Fantasy XIII meeting as well as into the studio. If you've ever wanted to see where your Final Fantasy games are made, here's your chance. And if you've always wanted to see a Square Enix helmet, hey, there's that, too!
