I do have a rather humorous story relating to FFX. A friend of mine thought it was too hard, to which I would laugh in his face at such a notion, and as such decided he wanted to use Game Shark to give himself a bit of an edge. He made all his characters super-powerful, but was unable to beat the game. Why? Because his Yuna was a goddess of power, and that meant all her Aeons were equally godly...so when he had to fight them all at the end, they would utterly wipe the floor with him. No contest.
But let me just say this, above all else, HERE is why FFX was an absolutely shitty game: it is literally impossible to lose against the main boss (Yevon) unless you kill yourself...TWICE! The disappointment felt while fighting the main boss cannot be calculated by human minds...I mean really? You're granted Re-Raise for your entire party and the only attack Yevon uses is gravity magic, so once you're down to 1 life it does no damage and basically lets you limit break all you want? Laaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaame.
