Ok, so I just finished the Thirteenth Cycle in Dissidia Duodecim.

As the end credits rolled, my eyes widened as I heard the theme for FFXIV! (No, not the song Answers, the stuff we heared during trailers and character creation.)

So what I'm wondering is if this is actually a subtle tip of the hat to FFXIV's existance, or if that very music was used in an earlier title?

Can someone enlighten me?
