I'm not saying FFVI isn't broken. It absolutely is, but not to the same degree as FFVIII if you ask me. Sure Edgar and his auto-crossbow are practically an easy button for the average battle, but it does little to help with bosses and unless you spend a lot of time overleveling the boss battles provide more challenge than FFVIII once you utterly break it and become pretty much invincible for the rest of the game. FFVI really doesn't compare until you learn Vanish and Doom, and at least that was removed in FFVI Advance. VII isn't really broken at all without a fair amount of knowledge you won't have your first time through, but it didn't really matter because even if you didn't try to break it it was still pretty damn easy.
Not to get totally off topic or anything.
