Re: Will I be able to transfer all my Sims 4 DLCs to Steam from Origin???
@littlemerg You need to buy the Sims 4 base game in Steam before you can buy any packs in Steam. At $5 U.S., this isn't a big deal, but it doesn't seem worth the hassle given that packs are on sale for the same price in Origin as in Steam. Plus, you'd still need to run Origin in the background while you played.
The first time you launch an EA game in Steam, or at least one that requires Origin to also be running, you'll be prompted to link your accounts. You can also go to most EA sites, for example ea.com (but not origin.com), click the login button, and click the Steam logo below the password field. After entering your Steam credentials, you should be prompted to link to an Origin account.
