Xbox Game Ownership

Unfortunately not mate, as Smutches said, its only available to your bro because he bought it on his account. The only option is for him to game share with you and you can have it on yours. Otherwise you will need to buy yourself a copy.

Hope this helps

If he bought it under his account, there is no way to transfer ownership to your account.

That games is not backwards compatible (which would be up to the publisher). So in order to play it on the One you'd either need another game pass subscription or you would have to purchase it for the One.

Per the Code of Conduct, you are not actually authorized to use the account that was left on the used Xbox, or any game licenses associated with it. I would suggest deleting the content, including the child account.

The relevant portion is below, and the full Code of Conduct can be found at this

link if you want to peruse the entire thing.

Don’t engage in fraud or unauthorized transactions. For example, don't:

• Lend, transfer, sell, or otherwise provide third parties access to your accounts or Gamertags
  

No, I have never owned gamepass.
