I've just heard this song from the Final Fantasy 13 demo when Lightning and Sahz were fighting that giant scorpion thing. It's such a cool song to play on the piano, so I hope someone could arrange it. You can listen to the full version here http://www.youtube.com/watch?v=xfu0XBf8kmk
This song can't really be done on piano; there's too much going on at once for 2 or even 4 hands to play. However, we might be able to make a sheet of the main melody only. Even then, it'd be really tough to play. :-\ Is that alright?
Of course!! :D
