As you may know, SE has been running a competition to find Final Fantasy super fans. You have to make a 60 second video showing your devotion to the series. If you win you get free tickets to a Distant Worlds concert and your name in the credits for the next Final Fantasy XIII game and a couple of other things.
Here are the entries so far.
If you want to enter the competition yourself you still have a couple of days. (Make sure you read the right rules for your region).
See if you can spot FFXI bits in the videos ...
