I could post the entire freaking final boss fight of Persona 3, but meh.

""The moment man devoured the fruit of knowledge, he sealed his fate.

Entrusting his future to the cards, man clings to a dim hope.

Yet, the Arcana is the means by which all is revealed...

Beyond the beaten path lies the absolute end.

It matters not who you are...Death awaits you.""

And starting my replay of FF9, one quote springs to mind.

"Soft."

"Everyone here is after something - fame, notoriety, power, money. Me? I'll have the whole bloody lot"

- self made Lallafell and Syndicate member, Cicidoa Sosodoa.

Lots of good quotes here I think my favorite is "What sound will you make when you hit the ground? Think you'll hear it before you die?"

Salazar: But it doesn't matter now Mr. Kennedy! I've sent my right hand to dispose of you!

Leon: Your right hand comes off?

I enjoyed that quote :P

"Walton Simons: You can't begin synthesizing the vaccine without a universal constructor, and don't think we're going to just leave one lying around. Not after you blew up the one in Hong Kong.

JC Denton: I was never properly trained in its operation"

Deus Ex.

There are plenty more from Deus Ex, but I'll stick to the 1 quote per post rule :P

War, War never changes
