Only about 13 percent of video games published in the United States prior to 2010 remain commercially available today, according to a study published on July 10 by the Video Game History Foundation (VGHF). Phil Salvador, the VGHF’s library director, authored the landmark study, which examined 4,000 classic video games first released on the Commodore 64, Nintendo Game Boy family, and Sony PlayStation 2. Overall, Salvador concluded that legal access to historical titles was “dire” across all software ecosystems and represented a “crisis for the entire medium of video games.”
