FF6 is my favorite FF by far. Everything about it blows every other FF out of the the water. I would LOVE a remake with the same setting, characters, story, but I would also love updated graphics (1080p please) with more dialogue, and more to the story, more like a reworking of the game more than a remake. I wouldn't think of it as FF6 though, more like FFVI-2 (ugh brings bad memories of FFX-2).
If it wasn't reworked though, no, it's too beautiful/amazing as it is.
Oh and FF6 is the game I've spent the most on, I got the last copy at a funcoland back in the day; price: $86. I guess that's why I don't mind spending $63 on games these days while other people have been upset over it.
