As part of their larger Legacy of Music Campaign and as promotion for Theatrythm Final Fantasy Curtain Call, which will be available for the 3DS starting September 16th (September 19th in Europe), Square Enix will be hosting a Legacy of Music Contest. The object of this contest is to produce an arrangement / performance of the series Main Theme (yes,
this 'main' theme) using whichever musical instruments or not-instruments you so choose. The winner will receive a trip for two to a Distant Worlds concert, "AND MORE!" Check out
the submission guidelines if you're interested, and if you win, don't forget who wrote the newspost that inspired you :D
In addition, Square Enix has announced a free 14-day trial for Final Fantasy XIV: A Realm Reborn. There are some limitations involved of course (you cannot exceed level 20, for instance), but for anyone who has wanted the chance to poke around A Realm Reborn,
here's your chance. The only eligibility requirement is that you have not purchased the game before (or participated in Beta), but you can transfer a character created during the free trial to the full version of the game, should you decide to upgrade.
