You'd need to put Origin offline, launch the game and then after exiting the game put Origin back online. This way it works.But... if I'm not mistaken, once Origin detects there's an update available for one of your games, you can't play it unless you let it download and install the update. You can choose not to download it, but you won't be able to launch the game at all, right?
My Origin is offline since I don't know when... I play both the FIFA 16 and FIFA 17 versions that came off the disc.
