I didn't get a chance to discuss specifics of logging in and Origin accounts in today's chat and was reminded about it afterwards... There's a lot of work taking place across EA to unify more of our players and communities so that you won't have to have multiple accounts/usernames/passwords across a variety of games. The account that you currently use to log in to Sims 3 in the launcher or on thesims3.com will automatically become an Origin account if you haven't linked them already. This in no way requires you to use Origin, you are not forced to download Origin, and it is fully compatible for our players who use Macs. All this does is update your account to be compatible with Origin.
