Why did the chicken cross the road?
Because the plot demands it.
"It's sort of like... having a girl ask, 'Why do you think I'm not speaking to you?' and realizing your answer actually has no effect on whether or not a fight is about to ensue."
"Rather than offer you the illusion of free choice, I will take the liberty of choosing for you..."
— G-Man, Half-Life 2
"Sometimes video games ask you interactive yes or no questions. Don't be tricked by having two options. They're only teasing you with one of them. For example, you often get asked things like, 'Will you help the king?' If you answer NO, it'll say, 'Oh, but you must!' If you answer NO again, it will say, 'Oh, but you must!' This will go on until someone or something destroys the power lines outside your house. And don't think you can just kill the King to get him to shut up, there's no button for that."
"For the request that I will ask you now please reply with 'Yes' or 'Okay'."
— Anzelotte, Night Wizard
"You know you haven't got a choice, Shanoa. Let's not play games."
— Albus, Castlevania: Order of Ecclesia
"I am not allowed to make choo-choo noises when the DM tries to force the plot."
"I'll just keep asking until you say yes!"

I want to entrust you with this Pokédex
Will you use it to record data on all the Pokémon in Sinnoh for me?
I can stand here without speaking for hours. I'm a very patient man.
Let me ask you again...
—Professor Rowan, Pokémon Platinum
Steve: I'm the fucking Avatar. I've handled that rune twice, both times to do something a lot more fucking important than any stupid shit you've ever done. I fucking found that thing. I dug it out of a furnace while it was turned on. You're going to tell me, with a straight face, that you can't let me have the rune until I do some idiotic thing for you?
Selganor: That's right.
Steve: Fine. But the only reason I'm not killing you with a cannon right now is that I have a grudging respect for your enormous balls.
Ford: You have to be my field agent, Razputin. Are you ready?
Raz: No. Not yet.
Ford: *slaps Raz* ...How 'bout now?
"Why are we doing this again?"
"Because Matthew can be talked into anything."
Tom Nook: Isn't your current house just a tad cramped? We could build you a larger home. It could hold much more furniture, yes? So? What do you say?
You: Smaller is cozier!
Tom Nook: Oh, (player name)! Always the joker, hm? I know a young up-and-comer like you, (player name)... You couldn't possibly be satisfied with a house that small. not likely! So, the roof on your newer, bigger house... What color should it be, hm?
— Animal Crossing: Wild World
Shepard: Enjoy it, Joker. If we're stuck here, we might as well let them pamper us.
Joker: Does it breach uniform regs if I get that on a crew shirt? Because this is my favorite "you have no choice" choice ever.
"Any customer can have a car painted any color that he wants so long as it is black."

"I understand the common belief is that in epics like these, the hero has to die. But the phrase 'the hero has to —' anything in a game [...] that's built around choice and you picking your own destiny? It goes against everything [that game] is all about."
— Jeremy Jahns, in response to Mass Effect 3's ending
