New Features

See this post by SimsVIP

The Sims 3 Starter Edition/The Sims 3 Refresh

If you bought the base game after Sept. 2012, you have a version that needs Origin and an Origin account. It seems that since the patch, you can no longer start the game from any short-cuts you might have on your desktop.

The game needs to be started through Origin.. This means that the short-cut will start Origin only. You will then need to press PLAY on Origin for the launcher to start and on the PLAY button on the launcher to start the game.

Trying to find out what this is all about.
