The Stanley Parable
Have you played The Stanley Parable? I highly recommend it if you haven’t.
The Stanley Parable’s gameplay is simple. Most of the gameplay is just walking around, experiencing a somewhat dull office environment, and occasionally interacting with an object or two while a narrator (a non-playable character or NPC) narrates. The player repeats the “same” scenario again and again.
However, depending on the player’s choices and overall state of the game, the scenario will likely change in some way. Variations can include the narrator saying something different, a new opportunity or decision being available, or a different ending.
