"Microsoft Studios will enable you to give your games to friends or trade in your Xbox One games at participating retailers," the company added. "Third party publishers may opt in or out of supporting game resale and may set up business terms or transfer fees with retailers. Microsoft does not receive any compensation as part of this."
This gives publishers more power than ever to control the second hand market, but one wonders if any of them will exercise these draconian options for risk of backlash.
When it comes to loaning games to friends, the rules are a bit pricklier. There won't be fees to transfer a game to a friend's account, but there are two restrictions: "you can only loan a game to someone who has been on your friends list for at least 30 days and each game can only be loaned once." However, publishers can limit these options as well, if they so desire.
