-monster post incoming-
Unbelievably, nobody has posted any lines from Portal yet.
"Didn't we have some fun, though? Remember when the platform was sliding into the fire pit and i said 'Goodbye' and you were like 'NNOO WWAAYY", and then I was all "We pretended we were going to murder you", that was great."
"I wouldn't bother with that thing. My guess is that touching it will just make your life even worse.... somehow. I don't want to tell you your business, but if it were me I'd leave that thing alone. Do you think I'm trying to trick you with reverse psychology? I mean, seriously now. Okay, fine, DO touch it. Pick it up, and just stuff it back into me. Let's be honest. Neither one of us knows what that thing does. Just put it in the corner, and I'll deal with it later. That thing is probably some kind of raw sewage container. Go ahead and rub your face all over it. Maybe you should marry that thing since you love it so much! Do you want to marry it? WELL I WON'T LET YOU! How does that feel? Have I lied to
you? I mean, in this room? Trust me. Leave that thing alone.
"There was even going to be a party for you. A big party, that all of your
friends were invited to. I invited your best friend, 'the Companion Cube'. Of course, he couldn't come, because you murdered him. All your other friends couldn't come either, because you don't have any other friends because of how unlikable you are. It says so right here in your personnel file; 'Unlikable. Liked by no one. A bitter unlikable loner whose passing shall not be mourned.' SHALL NOT BE MOURNED. That's exactly what it says. Very formal. Very official. It also says you were adopted. So that's funny too."
There's a lot more, of course.
Baldur's Gate and Baldur's Gate 2 have some fantastic lines.
Minsc: Fool me once, shame on you; fool me twice, watch it! I'm huge!
Minsc: Swords! Not words!
Minsc: Evil 'round every corner...careful not to step in any.
Minsc: There is strength in numbers, and I am two or three, at least.
Minsc: The bigger they are, the harder I hit!
Jaheira (to the chaotic evil mage you can pick up early in the game, Xzar): You are amusing, in a what-the-hell-is-wrong-with-you kind of way.
Korgan from BG2: Be aware, Mazzy, I've something long, hard and low to the ground ye're free to touch and fondle. Child, no need to glare! 'Twas me axe I were referring to.
Jon Irenicus, the evilest bad guy ever created:
Life... is strength. That is not to be contested; it seems logical enough. You live; you affect your world.
Your actions affect so many others than yourself. You will come to realise how little choice you have. You will do what you must, become what you must, or others will pay for your cowardice. You *will* accept the gifts offered to you.
I cannot be caged! I cannot be controlled! Understand this as you die, ever pathetic, ever fools!
Dialogues:
Imoen: So, Valygar ...word on the street is that ya killed your parents. Is that true? Sounds pretty horrid, if ya ask me.
Valygar: You consider *this* acceptable casual conversation? Just walk up and ask someone if they killed their parents?
Imoen: Would you prefer to let the rumor mill have its way?
Valygar: I could care less what the people have to say about me. People have talked about my family all my life.
Imoen: Well, that?s a pretty sour attitude. You know, they say your face freezes like that.
Valygar: For someone who supposedly has her soul tainted by the evil of a dead god, you remind me considerably of a chipmunk with a sugar high and a death wish.
Imoen: Ooo! Funny! That?s good!
Valygar: I try my best.
Viconia: Minsc, that... tattoo on your face. Does it have tribal significance or did some nursery's fingerpainting class assault you with the blue pastels?
Minsc: I do not like the tone of your voice, Dark Elf. The face I have is the face the ladies love! Boo loves Minsc's face, too! Don't you, Boo?
edit: CRAP I FORGOT ANACHRONOX
Sly: Uh.... hey there. Boffo ship you got here.
Villain Rictus: I shall kill you.... WITH DEATH!
PAL-18: Wanna see my batteries?
A lot of the other lines just aren't as good without the fantastic voice acting.
Knights of the Old Republic has some amazing dialogue as well, especially with HK-47 and Jolee Bindo, but I think this post is long enough.
