"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. In addition, third party publishers can enable you to give games to friends."
"Microsoft does not charge a platform fee to retailers, publishers, or consumers for enabling transfer of these games. We designed Xbox One so game publishers can enable you to trade in your games at participating retailers."
