“Video games are more prone than other media to obsolescence. With each new generation of hardware and software, scores of titles are made unplayable. Music has suffered similarly, of course: vinyl morphed into cassette into CD into digital audio. But music, like films and books, is easily transferred to new formats. Video games, which rely not only on audiovisual reproduction but also on a computer’s ability to understand and execute their coded rules and instructions, require more profound reconstruction.”
