Why can I no longer play TS4 without internet?

The game will not run without Origin. Even with a desktop shortcut for the game Origin still engages. I have auto updates for Origin turned off so I always get a notification when it needs to update. When Origin updates it does not really impact the games you play. My Origin is always on unless I exit it down by the clock on my desktop. I play offline but I do it through the options menu in the game. It's under the other tab.
