Is this backwards compatible with xbox one and can this game be installed offline and...

Hi there,

you will need an internet connection in order to Install these games, the games won't be run from the disc, but backward compatible versions will be downloaded and installed. You will require the disc to play the games after they were installed though.

Also since you are offline your console could also need an update itself to make backward compatibility work.

See this link for more information:

Let us know the results

its the exact same with playstation

games have to be installed, just go offline for faster installs

xbox one does have backwards compatiblity with some games, not all as its up to the publisher so in gta v case they did a better version for the one so 360 is not compatible

If the games are backwards compatible, they will show as "Ready to Install" in your Games and Apps. If they are not backwards compatible, then you cannot transfer them to the One. You can see a list of backward compatible games here -

For digitally purchased games, as long as it is on the
backward compatibility list, the game will automatically show up in the "Ready to Install" list of the Xbox One so you can install and play from there.

It would depend on the games. Only games that are backwards compatible will show as ready to install. http://www.xbox.com/xbox-one/backward-compatibility
