Players who missed the first Theatrhythm Final Fantasy game can check out the expanded release dubbed Theatrhythm Final Fantasy Curtain Call when it releases on September 16th, 2014, though Japanese gamers have been at the leaderboards since April.
Still, this new Quest Medley trailer should get you off to a running start with details on creating a party, the different kinds of musical gameplay in Theatrhythm, and how quests open up new avenues of gameplay.
Good luck completely every track at the highest level though, especially if you're up against Nick Tan whose expertise astounds even a 3DS aficionado like myself. For our review of the original Theatrhythm, click here. We'll have more coverage of Curtain Call in the coming weeks.
