Your answe was correct.
And I'm pretty sure this one is from StarCraft, it's a dialogue between Reynor and Kerrigan.
New quote (from an all-time classic) is below.
(When meeting a certain NPC) "I was just wondering where you two were!"
EDIT: I'll be away for the next half a day or so, thus if anyone is quite confident he/she has the right answer, feel free to go on. Also, if no one guesses (right) in the next six hours, it's a free turn for someone.
(And in case there's no new quote by the time I'm here again, I'll post some hints for this one.)

OK, I see no guesses and also no new quote have been posted, so here are two hints: my quote is from a classic RPG.
It is said by a certain Duke.

Well, as there have still been no guesses, here's one more hint, and in a couple of hours, I'm going to post the answer.
Hint: the story for the game was written by a very well-known fantasy writer.

With no guess whatsoever... my quote came from Betrayal at Krondor, where Duke Martin says it.
Free turn for someone!

(Thick russian accent) "Do not risk your lives and the lives of your families for the sake of dubious profit."

STALKER Shadow of Chernobyl

You're correct.
For the record, if you're absolutely certain that you've got the right answer and/or have links to prove it, you can go ahead and post the next quote without waiting for confirmation.
If GamerKought doesn't post again in 3 hours, anyone can go.

Here's my quote since GamerKought hasn't posted his.
"At many outposts, a Sunstone sufficed, if the morning light
warmed the tall horns."

Aye. Your turn now

"This place has been hallowed by the blood of thousands of champions of the Light, many of whom were mortal, like yourself. Now the final battle against the Prime Evils draws near . . . and you must face it alone."

Diablo II. Tyrael.

No new challenge, so here's mine:
"I'm going to tear his leg off and kick him with it!"
Not entirely sure if it is exactly with those words, but those that know it will recognize it anyway... :)

3 hours, no response!
Hints: It's on the GOG catalogue and it was released in '98.

That was twice the difficult since Dinamic Multimedia published this game on Spanish, but... it is from Shogo: Mobile Armor Division.
