I got really tired of TS2, even though I had all the EPs and SPs. (Perk of being a SM as I certainly couldn't have afforded all of those otherwise.) However, all I have for TS3 is World Adventures, but I still play the game on a regular basis and am happier with it than I ever was with TS2. I love my "dollhouse."
I was happier with Sims 2 than I ever was with Sims 3 cause the building aspects were better with 2 than 3.
