Papers, Please – Tense Immigration Officer Simulation

Papers, Please is a tense simulation where you check immigrants’ papers—what makes the game’s mix of moral choices (letting in refugees with fake papers or following the rules) and time pressure (processing as many people as possible to feed your family) so emotionally impactful, and which decision (letting someone in or turning them away) stuck with you the most, especially when the game’s story unfolded through the people you interacted with?
