List of longest-running video game franchises

This is a list of notable longest-running video game franchises. To qualify for this list, a video game franchise must have seen regular releases for "at least twenty-five years", from a franchise's first release to its most recent. Only franchises that started out as a video game are listed; therefore, video games based upon other media are not listed. Ports, translations, downloadable content, re-releases, and compilations are not considered new entries. Remakes (i.e., games with significant differences in graphics or game play) and expansion sets which received retail releases are considered new entries in a series.
