world=store item worlds are not expansion or stuff packs they will not be in your Orign my games tab the code for the world should be redeemed on your the sims 3 account then downloaded from there and installed once installed it'll be in the main menu +new game you will still play from whatever game you normally play from
Origin
If you bought the world through the Origin Store, you'll be sent a code which you need to redeem at thesims3.com (NOT on Origin or your code becomes invalid).
