I AM PROUD OF YOU!!
Question: how do you know you defeated EVERY boss without a guide? (Just curious) Also, did you capture every esper? I think that's certainly doable at about the 140 hr mark.
Did you join the Hunt Club and defeat every mark, too?!
Did you do all the side quests and get all the legendary weapons, or at least get the Zodiac Spear?
If you did, my hat is off to you and I bow before your FF mightiness. It took me about 160 hrs to fully complete the game.
I agree about the tedius fighting system. I thought that the last couple of bosses, with + 8 MILLION hit points each, were just ridiculously silly battles!!
CONGRATS!!
