The Stanley Parable/Nightmare Fuel

Beneath its comedic exterior, The Stanley Parable is rife with both Nightmare Fuel and Paranoia Fuel with its surprisingly excellent use of Nothing Is Scarier and Controllable Helplessness.

• The Narrator's progressively manipulative and antagonistic behavior can get this way.
• The ending where you end up trapped in a cage and slowly move towards a crusher, while the second narrator cuts in and begs you to take control away from the game by exiting it, her voice growing increasingly desperate, and then is suddenly cut off by the crusher smashing into you.

Press escape, and quit the game. That's the only way to win this game. Do it now, and it will be your only true choice. If you keep going, you'll be walking someone else's path. Whatever you do, don't let time choose for you! Don't let tiSMASH

• The "Pawn" ending, where the Narrator restarts the story and changes it so that the monitor commanding Stanley never shuts off to give him an opportunity for escape. Thus, he is left a mindless slave as it dictates his every action, while the Narrator creepily describes how it's all hopeless and how Stanley will never escape, and then the monitor suddenly displays "Please die" and everything goes black...
• The Games ending. The Narrator, so fed up with Stanley, essentially abandons him in an unfinished netherspace of half-finished environments and utter darkness. Stanley plunges down and lands in the setting of the original mod- decimated, and devoid of light... and he's left alone there, presumably forever.
