"No offense, but I'm going to offend you..."
Anyway, the newer translation is far more 'accurate' with what it should have been many years ago. It just unfortunately changed quite a bit about the story/characters/spells/etc now that it was done 'correctly'. Extra content isn't useless to all. If you feel it is, that's fine, but not to everyone. The newer version doesn't really have anything that "breaks" the game compared to what could have been done in the original.
Take it easy with the insulting, elitest attitude, allusions to emulation which can be inferred as piracy and take some time to read the rules - which clearly state you can talk about emulation. Speaking of, FFT has a rather large mod and emulation community which I encourage all to take a look at if you really enjoy the game and want to get more out of it.
