Question about installed games

Could i copy an installed game from my hard drive with horizon, then transfer it back later and would it still work? Same console of course.

That is a very good question. I do believe you can copy a game using horizon and then transfer it back as long as the license is on the purchased console.

yes you can

Thats what i figured.

I just tried transferring it back, its recognized when i go to storage, and in my games library, but when i try to play it, with the disc in, it says to inert the game. When i click x on the game from the dash it gives me the option to install.

You are talking about installed from disc?
