Watchdogs is not backwards compatible. So you would have to purchase the One version in order to play it on the One. https://majornelson.com/blog/xbox-one-backward-compatibility/

What game is thw one hat doesnt show up?

Which game(s) are you having trouble with?

The Home Xbox system allows one person to set a console as their Home Xbox and that allows any other profile on that Xbox to download and play any of the Digitally bought games from that profile.

Digital licenses go with the profile that purchased them.

Any console that is set as a profiles Home console will show their digitally bought games in the ready to install section automatically on that console.

So in your situation if you have your Xbox set as your friends Home Xbox their digitally bought games would automatically show up in your ready to install section on your console, if their are no games showing up in your ready to install section then that
profile they gave the sign in information for does not have any digitally purchased games on it.

You can sign into an account at account.xbox.com and go to the my games link at the top and it will show you any Xbox One games that the profile you are signed into on that website has on their account.

Xbox had several promotions regarding Minecraft on Xbox 360 and getting the digital copy for Xbox One if you purchased it on Xbox 360 if you purchased your game digitally during this game promotional. The game should show up in your ready to install games
on Xbox One
