This is brilliant. Steam user Snakeeeater337 has created a mod for Sid Meier's Civilization V that makes Papers, Please 's Arstotzka a playable nation in the game, with its own units, special traits, and even a new map.
Since Papers, Please never establishes the identify of the Big Brother-esque leader its Eastern Bloc-inspired nation, the mod's Arstotzka is led by "Glorious Leader." Its custom unit is the Border Guard, which has no maintenance cost and a 50 percent combat bonus in friendly territory. Outside friendly territory the Border Guard is weaker than a regular Rifleman unit. The custom building, appropriately, is a Border Checkpoint, which reduces the spy stealing rate by 33 percent and has no maintenance cost. You can also fill its specialist slots with Immigration Inspectors, who provide three gold each turn.
In addition, the mod also adds a map based off the one that appears on passports in Papers, Please, and ads Cobrastan as a City-State.
