I could have sworn that was Rambo :-D

"An open mind is like a fortress, with it's gates unbarred and unguarded"
"We are shaped by fate just as we shape it"
"The warriors of the Inquisition are yours to command!"

there is a plenty of Sisters of Battle quotes missing, I wonder why noone did not complete it :/

cause they are just marinewannabeweaklings and do not deserve attention of real marines (i think they put SoB in game just to put something inside, personaly I don't like them).

I always thought that the SOB were crap, in tabletop or in DOW. Chickmarines with a flamer fetish aren't really that interesting and not diverse enough from marines in general.

I just love this:

Any quote from Minsc is golden.
Oblivion
"Even St. Jiub, who drove the cliffracers from Vvardenfell, has fallen to the daedra hordes." (Like everyone, I despised cliffracers.)
And from Deus Ex, my favorite game conversation:
Raphael: I wish to hell they'd give us the all-clear.
Jake: You making a play today?
Raphael: Nah, scavenged some copper wiring. Wanted to get back and try it out on the sculpture.
Jake: Christ, you and the sculptures. What's this one called?
Raphael: "The Man Who Was Thursday."
Jake: Makes as much sense as the last one. What was it called? "Napoleon" something or other?
Raphael: "Napoleon of Notting Hill."
Jake: Doesn't seem much use for sculpture today.
Raphael: There's always tomorrow.

Jupiter: "You know what I find most uncomfortable about you, Riddick? How comfortable you are. Here. In Butcher Bay, I mean. Caged inside this slam."
Riddick: "I play the hand I was dealt. And then I cheat."

hehe...
Abbott: "You're messin' with the natural order of things here, Riddick. As a result someone can get hurt. And we don't want that."
Riddick: "Speak for yourself."
Got to love that game...
