Papers, Please (Online Graphical Adventure Game)

"Papers, Please is a graphical adventure game developed and published by 3909 for the PC (via Steam, GOG.com, and the Humble Store) on August 8, 2013.  Described as a "Dystopian Document Thriller", players control an immigration inspector for the fictional Soviet-style nation of Arstotzka during Cold War-era 1982 (right after a six-year war with neighboring Kolechia).

As inspectors, players have the powers (and responsibilities) to control the flow of people entering Arstotzka through their half of border town Grestin.  Players must inspect the credentials of incoming civilians (noting any irregularities) and either accept or deny entry.  As days go on, the rules of entry change (adding further complexity and difficulty) and players are introduced to new techniques and technology to detain terrorists, smugglers, pimps, and other undesirables.  Players are also tasked with processing as many people as possible in order to earn money to feed their family and keep them warm through the harsh winter.

Throughout the story, national and international politics become complicated, and players must make difficult decisions (leading to any one of the 20 possible endings)." - Game Wiki, Sept. 3, 2013.
