GOG has launched a Preservation Program to ensure retro games remain playable for current and future generations, committing resources to maintain compatibility with modern systems. The program starts with 100 titles, including Diablo, System Shock 2, and Resident Evil 1-3, with plans for expansion. Benefits for purchasers include compatibility assurance, comprehensive content, technical support, and offline access to installers. GOG aims to acquire all games no longer updated by their original publishers, addressing the issue that 87 percent of games released before 2010 are no longer playable. The program positions GOG as a leader in video game preservation.
