Game preservation is the cultural movement dedicated to ensuring that video games remain accessible and playable for future generations. Unlike books or films, games face unique preservation challenges: they depend on specific hardware that degrades, online servers that get decommissioned, DRM systems that stop authenticating, and proprietary formats that become unreadable. Organizations like the Video Game History Foundation, The Internet Archive, and countless volunteer-run projects work to archive games, documentation, source code, and the cultural context surrounding them. The movement exists in legal tension with copyright holders who often oppose preservation efforts even when they have no plans to re-release the content.
