In response to concerns surrounding the possibility of DRM measures to hinder the resale of used games ( and in particular , the initial DRM policies of Xbox One , which did contain such restrictions ) , Jack Tretton explicitly stated during Sony 's E3 press conference that there would be " no restrictions " on the resale and trading of PS4 games on physical media , while software product development head Scott Rohde specified that Sony was planning to disallow online passes as well , going on to say that the policies were designed to be " consumer-friendly , extremely retailer-friendly , and extremely publisher-friendly " . After Sony 's E3 2013 press conference , IGN responded positively to Sony 's attitude towards indie developers and trading games , stating they thought " most gamers would agree " that " if you care about games like Sony do , you 'll buy a PlayStation 4 " . PlayStation 4 's removable and upgradable hard drive also drew praise from IGN , with Scott Lowe commenting that the decision gave the console " another advantage " over the Xbox One , whose hard drive can not be accessed
