Turns out you’ll only be able to share each one with only one person. Ever.
Give your games to friends: Xbox One is designed so game publishers can enable you to give your disc-based games to your friends. There are no fees charged as part of these transfers. There are two requirements: you can only give them to people who have been on your friends list for at least 30 days and each game can only be given once.
So if I give a game to my friend, it can never be given to anyone again. Unbelievable. Hope you weren’t planning on sharing Xbox One games with your friends!
