Amazon is making it easier for Prime subscribers to play games, the latest effort to extend the appeal of a loyalty program designed to keep shoppers engaged. From a report: The world’s largest e-commerce company on Monday gave its more than 150 million Prime members access to free video-game content, eliminating a step that required them to link their Amazon account with one on Twitch, the company’s live-streaming subsidiary. The service, once known as Prime Twitch, is now called Prime Gaming and offers special in-game perks and free downloadable PC games. Prime, which now costs $119 a year in the U.S., began as an unlimited free-shipping program designed to entice customers. Amazon has since tacked on a suite of digital perks, such as video streaming, music and photo storage. Members spend far more on the retail site than non-members, surveys show.
