I got it two days ago and it is, quite literally, the most addictive music game i've ever played. It not only floods me with love for the series, but lets me peek in and get curious about the games i've yet to play. Between the little, pathetic plot, to the annoying act of trying to get new characters, it is a wonderful addition to any persons final fantsy collection. I love it. A lot. The miltiplayer is my favourite part- it gives the player a chance to do a lot of the harder songs with people much higher level than you (it means that you can succeed as well as gain levels). It has become my favourite 3ds game.
So, on that note, i have a game to play. I recommend it to everyone and if you have it and are coming to Ikasucon in Fort Wayne, Indiana, I will hunt you down and play a round or two of 'Lets go get some Dark notes' with you.
