FFX-2 was easy the whole way through, but this isn't the forum for that.

Personally, I left Auto-Targeting off, when I played FFO, mainly because it felt more like playing the original. It ups the difficulty, if only by a small bit, and does, indeed, keep the battle tactics intact.

Otherwise, it would simply be holding down one button, as Unne had said. Sure, you can still target other monsters to "optimize damage", as some of you had said, with the Auto-target on, however, when you're just fighting to level up, I don't believe many bother with that. Yet, when that option is left off, then it forces you, the player, to pay attention, even if each monster only takes two hits to destroy.

Perhaps it makes things more "obnoxious", but I suppose that's what makes a classic a classic.
