Incredibly balanced, reasonably challenging, fixes every issue, almost perfect. There are no useless characters.

Have you played this yet? Did you manage to kill Kefka? I got supremely lucky after I murdered Gogo just for Relm to replace him. Struggled but succeeded with Sabin / Setzer / Terra / Relm. This is the best possible version to play. Plus there's a nice dose of sarcasm installed. Especially when you try and snap up Water Rondo.
