My Tokyo Game Show hands-on session with the upcoming 3DS game had me playing Final Fantasy V songs. In battle mode, "Gilgamesh" had me feverishly tapping out rhythms on top difficulty. Other than some slight visual touches there looks to be nothing new about this mode. I guess that the added songs will add the new in this case.
The original track list returns, but new stuff from games like Final Fantasy: Crisis Core and Final Fantasy XIV have been added. The feel of this game changes quickly when you don't know the songs. A new tune from Lightning Returns had me fumbling and failing, putting me in my place.
On the Field Stage Music side of things, I redeemed myself with Final Fantasy V’s "Airship Theme." I love the way these stages look when doing the airship thing. The action is slanted so that it looks like you're flying into the left side of the screen. The play isn't any different from the standard flat play, but the dynamic look changes the feel. And happy little moogles popping out to celebrate doesn't hurt, either.
You don't need my TGS preview to know that you'll want this game. It's everything you liked, upgraded a bit, plus new songs from Type-0, Advent Children, FF:XIV and more. You're getting 200 songs, 60 characters, a new quest and more. Add in a new two-player competitive mode that has proper taps sending junk to opponents (like a puzzle game) and you have one hell of a update.
The Japanese release of Curtain Call is slated for Spring 2014. I hope ours comes not too long after.
