Square Enix's Theatrhythm: Final Fantasy hit store shelves in Japan yesterday only to fly off soon after. According to reports, the music game for the 3DS sold out as soon as stores opened up for the day.
This is good news for Square Enix, who also have additional downloadable content available for purchase at an introductory price of 100 yen a piece. Square Enix won't have another shipment ready until the the 25th of this month.
Square Enix have yet to announce if the game will be made available outside of Japan. Our fingers are crossed.
