The best part of any rhythm-action game is getting good enough to play the mental-fast songs. Theatrhythm Final Fantasy will have such songs as we're pleased to see in this new trailer.
With over three minutes of gameplay footage you can work out how the game plays. It appears similar to Ouendan (AKA Elite Beat Agents), with a combination of taps and dragging motions on the touch screen with the stylus in time with the music.
Announced back in July, it's a 'theatre rhythm action' game set in the Final Fantasy universe, with music from across the series right up to FFXIII.
