Sony doesn't own Sephiroth or FInal Fantasy VII. This could easily be on the other platforms too. Please tell me you went on Microsoft's forum to make this suggestion too and just jump to Sony when they don't own any aspect of FFVII.
(Random) They should make FF7 costumes of our favourite characters on home, would be great . Also this should be moved to Final Fantasy series section (no idea why its on home) lol.
Maybe shoot it over to SE, maybe they can use this to throw at you and slam the door shut before yelling we're not remaking ff7 lol. Just kidding, I for one would like a complilation of the whole story with adding some spinoff featuring more Zack and Sephiroth.
