Papers, Please is one of the most unique, thought-provoking games to have been released in recent years. The game is estimated to have sold over 2 million copies and has frequently been used as an example of the "games as art" argument, as well as winning several awards, including a BAFTA.
All of those accomplishments are made even more impressive when you learn that the game, which puts players in the role of a border control officer in a fictitious dystopian country, was made single-handedly by one man: Lucas Pope. Pope used to work with Naughty Dog, the studio responsible for games like Uncharted and The Last Of Us, but decided to leave the company to focus on smaller projects.
Inspired by the works of George Orwell and movies like Argo, Pope decided to make a game built around a passport control worker who has to decide when to follow the rules and when to break them. Papers, Please included some emotionally-draining moral choices and a deep story with twenty different endings to unlock.
