Possible to share games between 2 household xbox one's?

I haven't done this myself, but to follow up on I08Stitches' post, I follow a blogger who has a setup like yours. He has the Xbox he uses set to be HIS SON'S Home Xbox, and his son's Xbox set up to be HIS Home Xbox. He signs in on his own console; his son
signs in on his son's. They both have access to all the games.

I know all of the game's I've purchased on my living room xbox are available on my basement xbox. The one caveat to that - one of the xbox's has to be tagged as your "HOME" xbox, which allows any user on the system to play the games purchased - the other
xbox games can only be played by whichever gamertag purchased the items. This can cause some problems if your gamertag was used to purchase and you son has to sign in as your gamertag (as you can't be signed in on both xboxes at the same time).

If you currently only have one console in your household and wish to purchase a 2nd one. You will be able to share your subscriptions with the 2nd console.

You will need to gameshare with the 2nd console. Check the link below to see how to set up gamesharing between 2 consoles.

• No, Xbox does not allow you to game share with people outside your household. Game sharing is a feature that allows family members or friends living in the same household to share games and Xbox Live Gold memberships on one console. Sharing your games or memberships with people outside your household violates the terms of use and could result in account suspension or other penalties.
  

You can only share games in the same household on one console. If you share games to another household, then you are basically breaking Xbox rules, and can be suspended or banned for doing it.
