Gaming Trivia Day 21

Hello! For the last day of "Quote Week" I decided to ask one of my friends for a quote. I have no idea how easy this one will be, though it's from a very popular game, so I won't be surprised if it gets answered quick. I've also never played this game, so I'm just going to ask for the game rather than the character because I feel like that will be easier for me to also keep track of. Good luck to everyone!

What game does this quote come from? "A man chooses, a slave obeys."
