FFVI is one of my very favourite FFs, and Kefka is the best villain in the world (apart from Hank Scorpio in The Simpsons), but I do admit the game gets less interesting in WoR. I've never actually completed the game myself so I don't know how interesting it is at the end, but I always found the game slowed down considerably after Celes tries to (SPOILER)kill herself.
