Re: I want to play Sims 3 pets that I bought from Steam in Origin.

@texantravis  I've merged your post with another thread for this issue.  Please see the post immediately above yours for more information.

If you'd rather skip this process and play through Steam, you should be able to do so, although I'm not completely sure that the newly announced China-specific version of Steam offers Sims 3.  The global one should though.
