Edit: There seems a way to actually play sign-in games offline, the steps are on the solution.
Games that require you to sign in to Origin such as The Sims 4 and Dragon Age: Inquisition will only start if signed in to Origin. If not connected to the Internet without Origin running, the game will not start as Origin won't sign in. Basically, you need an Internet connection to start games that require Origin sign in. Otherwise, the game won't start until you are connected to the Internet.
On Steam, if you are not connected to the Internet and you start Steam, it allows you to run it in Offline Mode assuming if Steam remembers your account and you can run games that require Steam which most non-EA or non-Unisoft games do. However, Origin doesn't provide such an option even if you told Origin to Remember Me. I've learned that to put Origin in Offline Mode, you have to be connected to the Internet and signed in to Origin. This might be annoying on laptops if you started Windows or OS X and you're not connected to the Internet making you unable to play your games. I did report this issue from the thread in The Sims forums back in November 8, 2014 and was told to post the issue here but I haven't gotten the chance.
Here's the results when I try to play The Sims 4 and The Sims Medieval:
Games that don't require Origin sign in such as The Sims 3 (1.67) will start without issues without an Internet connection but others like The Sims 3 (1.69) and The Sims 4 won't.
