I was disappointed in this title. Being Final Fantasy, I thought there would be some sort of RPGness to this. Wrong. You do pick a party of four with magic abilities and items but I didn't see how any of the magic or items really did anything. The whole jist is that you choose which Final Fantasy story to "relive" (the level you will play), run through 3 rhythm games that would only be difficult to someone under 6, and voila, level complete. That means that each level takes about 5 minutes to complete. If you actually waste your time and complete all the levels, you are talking about an hours worth of time (that you will never get back). I enjoyed this game for about 15 minutes before putting it back in the mail.
I'm a musician and I love the Final Fantasy series. The music from the games have helped me find my muse. With this game, I find myself playing at 2 am in bed when I can't sleep. I've had yelling matches with my son over his DS so that I can play with it. My only problem with the game is the Chaos Shrine which the songs are a little fast for me because my eyes are a little slow. That's more of a user/operator issue than the game itself. If you or someone you know loves music and Final Fantasy, this is a game to get them!
