In short this game is a perfect combonation of Guiter Hero style mixed with Final Fantasy in 3DS form.
I have played 6 Final Fantasy games
and none of them I have been pleased with
as all of them I have counted as failures
I have even gone so far as saying Final Fantasy is an overrated and overhyped franchise
but thanks to Theatrhythm Final Fantasy
I can finally say "This Final Fantasy game didn't suck!"
