If there are any fans of FFVI, do yourself a favor and look for "Final Fantasy VI: Brave New World"
it's a romhack that greatly rebalances the game and makes it fairly challenging. Evade actually works, as do Vigor and Stamina. It was designed so everyone can't learn every spell. Instead of everyone having access to every esper, each character has a select few they can use. The monsters and bosses have all been re-tuned and a bit of the dialogue cleaned up (although the guy who wrote the dialogue has a few parts he added that were really, really dumb.)
But yea if you're a fan of FFVI it's definitely worth checking out. I'm not gonna link it since it's a romhack, but it's goddamned Super Nintendo so go use your google fu and check it out.
Also Kefka is the shit.
