These are seven pieces from Final Fantasy Legend aka. Makai Toushi SaGa. Game by Squaresoft, music composed by Nobuo Uematsu.
0:07 Prologue
1:26 Main Theme
2:27 Forbidden Tower
3:21 Wipe Your Tears Away
5:14 Requiem
6:26 Top Floor
7:31 Epilogue
In my opinion, it's one of the most underappreciated, mistreated and misunderstood games of all time. Its soundtrack is also one of Uematsu's lesser known works. I was amazed at how well the music translates to the piano, almost as if it was written for it.
Please do not take personal offense from this video. It is meant as a paraphrase of some of the motifs of the game's story.
