I would have found it a much more emotional and arguably better ending if magic was no more in the world and Terra had died because of it.

I always thought Final Fantasy VI had a much more open ending than IV and probably deserved that sequel that IV got. Not to say it wasn't good, as I love IV, but I thing VI needed it more.

Otherwise, I agree with Oscar on how the other characters go on with their lives. Of course Gogo is the same one from V. =P I hope we see him in a future installment.
