Konami to the player, Gradius 3

"Doctor Freeman, you really shouldn't be out there. At the moment of synapse as I teleport this chamber will be bathed in deadly particles that have yet to be named by human science. Perhaps when I have the leisure to do the work myself, I'll name one of them after you; that way you won't be completely forgotten. When the singularity collapses, I will be far away from here - in another universe, as a matter of fact. You on the other hand will be destroyed in every way it is possible to be destroyed, and even in some, which are essentially impossible!" - Doctor Wallace Breen, Half-Life 2

"My country lay within a vast desert, when the sun rose into the sky a burning wind punished my lands, searing the world. And when the moon climbed into the dark of night, a frigid gale pierced our homes. No matter when it came the wind carried the same thing... Death. But the winds that blew across the green fields of Hyrule brought something other than suffering and ruin. I coveted that wind, I suppose. It can only be called fate... That here, I would again gather the three with the crests... That I should lay my hand on that which grants the wishes of the beholder... That when power, wisdom, and courage come together, the gods would have no choice but to come down... The power of the gods... The Triforce! He who touches it will have whatever he desires granted!" - Ganondorf, The Wind Waker

Long but oh so good

The right man in the wrong place can make all the difference in the world. So, wake up, Mr. Freeman. Wake up and smell the ashes... - G-Man, Half-Life 2

KOTOR probably has my favourite quotes in a videogame, some of them are genuinely laugh out loud material:

"I hate you old man" - Main character

"You're not gonna get me, Fishy. I'm safe behind five-no- TEN centimeters of Durasteel. No food for Fishy!" -Whispering Locker

"Say, now that we've got the Star Map do you think we can leave this planet soon? I've got sand *everywhere*!" - Mission

"Main character: Can you understand what the Jawa is saying, HK-47?

HK-47: There is a 98% chance he needs your help with something.

Main character: And the other 2%?

HK-47: The other 2% states he is asking for trouble and needs to be blasted, but that's probably just wishful thinking on my part, master..."

Gex - "Geronimo"

That's the first time i heard it.

 That's probably the best one.

GLaDOS from Portal:  "Remember that time we tried to kill you by putting you in fire and you were like NO WAY? That was great."

That one is funny haha.

"Relax. I'd rather not piss this thing off." - Master Chief

"Wake up! Can Hyrule's destiny depend on such a lazy boy?" - Navi to Link in OOT

EDIT: "The sky is ominous" - Rat Chick in FF9 (the sky in the background is bright blue)

"I humbly accept this task" _collete TOS
