Third-party sellers have become a huge part of the Amazon experience, offering customers a wide variety of products at knock-down prices. Video games are part of that equation, which is inevitably pulling business away from specialised UK retailers such as GAME. In response, the latter is launching a direct competitor today called GAME Marketplace, which gives independent merchants the chance to sell video games and other related merchandise through the GAME website. At launch, this includes clothes, smartphones, movies, comic books and a ton of other paraphernalia. Video games do feature, but they're mostly older titles and retro classics that aren't going to affect GAME's core business.
