I'll post some right away. All from Metal Gear.
"Wolves are noble animals. They're not like dogs. In Yupik, the word for wolf is "Kegluneq", and the Aleuts revere them as honorable cousins. They call mercenaries like us "Dogs of War". It's true, we're all for sale at some price or another. But you're different. ...untamed... solitary. You're no dog... You're a wolf."
-Solid Snake
"Snake, we're not tools of the government or anyone else! Fighting was the only thing... the only thing I was good at, but... At least I always fought for what I believed in..."
-Gray Fox
"A cornered fox is more dangerous than a jackal!"
-Gray Fox
"You are the most impressive collection of freaks outside of Foxhound"
-Ocelot
"Without full air, sea and land support Arsenal is nothing more than a gigantic coffin!"
-Solidus
That's all for now. I love Metal Gear games.
