The Stanley Parable is a first person exploration video game about Stanley, but it’s also not about Stanley. If that’s confusing, the official description won’t be of much help:
You will play as Stanley, and you will not play as Stanley. You will follow a story, you will not follow a story. You will have a choice, you will have no choice. The game will end, the game will never end. Contradiction follows contradiction, the rules of how games should work are broken, then broken again. This world was not made for you to understand.
The Stanley Parable, originally a 2011 Source mod, is available on Steam for both PC and Mac.
