Some of my favorites:
Apparently some people think FF II was a terrible game, I for one think it was pretty great and it has some really nice quotes.
"All those who live must some day die. It is our fate."
―Minwu, Final Fantasy II
"Reluctance to forgive has long been a human failing. It is man's nature to sin, yet you answer sin with violence upon violence. Is that not itself a sin?"
―Emperor Mateus, Final Fantasy II
"Guy speak beaver."
―Guy, Final Fantasy II
"The gift that Noah gave Xande--mortality--is the greatest gift of all."
―Unei, Final Fantasy III
"Being able to die is a great gift...? I still don't get it..."
―Luneth, Final Fantasy III
"But anger never bears true strength, and it blinds you."
―Rubicante to Edge, Final Fantasy IV
"Enough expository banter! Now we fight like men! And ladies! And ladies who dress like men!"
―Gilgamesh, Final Fantasy V
"I heard a meteorite landed near Tycoon. Too bad it didn't land on my mother-in-law..."
―An NPC in Carwen, Final Fantasy V
"To tell you the truth... I worry too much about what others think of me. I hate that side of me... That's why I didn't want anyone to get to know me. I wanted to hide that side of myself. I hate it. Squall is an unfriendly introverted guy. It made it easy for me when people perceived me that way. That's a secret between you and me. Got that?"
―Squall, Final Fantasy VIII
"This is reality. No one can help you. Sit back and enjoy the show."
―Edea, Final Fantasy VIII
"Peace is but a shadow of death, desperate to forget its painful past... Though we hope for promising years. After shedding a thousand tears, yesterday's sorrow constantly nears. And while the moon still shines blue, by dawn, it will turn to scarlet hue."
―Kuja, Final Fantasy IX
"Now! This is it! Now is the time to choose! Die and be free of pain or live and fight your sorrow! Now is the time to shape your stories! Your fate is in your hands!"
―Auron, Final Fantasy X
"We call it Sin."
―Auron to Tidus, Final Fantasy X
"Sin is cursed. Sin prays. It curses its form, it prays for dissolution. Sin sees dreams of its own destruction. Sin is looking at us. We live in a fading echo of time left us by the destroyer. Free him from Yu Yevon. Free him....the fayth that has become sin."
―Valefor's fayth, Final Fantasy X
"I always knew Fran didn't take well to being tied up. I just never knew how much. (to Ashe) How about you?"
―Balthier, Final Fantasy XII
Balthier: "You made your Nethicite for this. You mimic your Occuria's Stone for what? To become a god yourself?"
Dr. Cid: "On whose shoulders better to stand than those of the would-be gods!"
— At the Sun-Cryst, Final Fantasy XII
"But, you know, no matter how hard we try, we can't change the past. There's nothing that can bring them back. Still, sometimes, when I close my eyes… I can see them so clearly."
―Penelo, Final Fantasy XII
"The Illusions of the past. You think to have cast them off, only to find them years later, unwearying, unrelenting. The past can bind a man as surely as irons."
―Reddas, Final Fantasy XII
"You don't believe in anything. You gave up on life before you were even born. Sat poisoning Cocoon from the inside, waiting for someone to come and destroy you. Sure, you think the end of the world is salvation. All you care about is death's release. So take it, and leave the rest of us alone. We don't think like that. When we think there's no hope left, we keep looking until we find some. Maybe Cocoon is past saving, but it's our home. And we'll protect it or die trying! We live to make the impossible possible. That is our Focus!"
―Lightning to Orphan, Final Fantasy XIII
"All this dampness is damp."
―Sazh Katzroy, Final Fantasy XIII
This list was longer than I had intended.
