I have installed all my Sims 3 EPs again except for one which had problems ending during installation so I gave up with it. I had also bought a few on Origin.
I had decided to install only Pets but I changed my mind. Generations had trouble ending the installation.. it kept saying "Retry" and it didn't seem to continue so I'm not using that.
I have all of them except Supernatural. Not a big fan of that.
i only have world adventures!
