Aisle

Aisle is a well-known game with a strange mechanic; you are inside a grocery aisle shopping for food, and you only get one action before the game ends.

One-action games such as Rematch or Pick up the Phone Booth and Aisle started appearing soon after Aisle's publication. It became a mildly popular genre, and still is.

What makes Aisle successful? Part of its success is its specific details; you're not just in any aisle, you're by the gnocchi, and gnocchi remind you of your trip to Italy; the woman by you isn't just a stranger,or is she?

Another reason the game is fun is that the endings contradict each other; the story of who you are and what your past is actually changes based on your decision, so that your one action generates an entire past.

The third reason I think many people enjoy it is the wide variety of moods in the endings, from pathetic to hopeful to violent.

This is a game that everyone should play at least one time.
