I've been wanting a FF7 Remake for years. Now I don't think I have any hope left, but I'd definitely love a PS3 version of FF7 (I wanted a PS2 version, but sometimes you must just stop dreaming =P).
But I think it's a great idea adding Advent Children events after you beat it! =O
*Can someone remind me the name of those 3 new characters from the movie?*
Well, a sub-game in which you play as any of those three accomplishing things for the reunion would be cool =P and you'd have to fight Cloud and the others
or something like that. I think that'd work as a minigame.
