Game Preservation

Game preservation is the effort to keep a game playable, or at least legible, against the several independent ways a game stops existing.

Games rot for reasons that stack. Delisting removes a title from sale without removing it from libraries that already own it, which quietly stops being true the moment a platform itself shuts down. Licence expiry hits soundtracks and licensed likenesses on a clock the game's own code doesn't run on — a needle-drop-heavy game can outlive the rights to its music. Server shutdown ends whatever ran server-side outright — matchmaking, live events, save validation, anything the client requested rather than computed — though how much of a game that takes with it varies: many titles stay playable offline or in reduced form, and where they do not, private servers and Emulation of the original service have become a standard preservation practice, rebuilt from captured traffic and client code. Hardware and DRM dependency means a game tied to a specific console revision, activation server, or Code Signing check can become unplayable while every file survives intact — a version of Planned Obsolescence the publisher didn't have to design on purpose.

Two different things are being preserved and they diverge quickly. Preserving the artifact means keeping the files, verified against a Hash Function so a copy can be trusted; preserving the experience means keeping it playable end to end, servers, matchmaking and content drops included, which is a much larger and often impossible commitment. A Live Service Game is close to unpreservable by the second definition: its content was never a fixed thing to archive, only a state the servers held at a given moment, and its Provenance — what version a player actually experienced — dissolves the moment the servers go dark.

Legal ambiguity slows all of it down, the same Right to Repair-adjacent territory modding and emulation projects work in without a settled rule protecting them.
