Re: Have Sims 3 base game (not starter pack) can I buy other expansions?

@cmirabien  The Starter Pack requirement is only because that's what Origin sells these days, not the standalone base game.  You don't need the Starter Pack, or the packs it includes, to buy more packs or play them, or at least you shouldn't.  So yes, you can buy other packs without worrying about it.

If you do run into any trouble, please report it, since that's not how Origin is supposed to work.
