It will probably start around June 25th, when the new Sims 3 Island Paradise comes out.
I'm planning to run a resort in the new EP. So maybe when Sims enter my resort, I can choose them to make it seem like a surprise enrollment for The Sims 3 Big Brother.
Also, when I choose 13 Sims, they're not all living in a house. Each Sim will have a photo taken and I will post the cast in the group! ^_^
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.
