Happy Birthday, Sims! I started playing after Sims 2 came out. I would watch my daughter playing it and she finally talked me into trying it. I was hooked! I haven't stopped buying and playing the Sims series since then. I can't say which pack is my favorite as I enjoy all the packs in all the games. I loved getting seasons in 2, 3, & 4, and really enjoy World Adventures in 3. But I wouldn't enjoy them as much without the gameplay and items from all the packs I own! I still play 2, 3 as well as 4 when time allows. If I get bored in one I am playing, I return to another. Sims Medieval is great too and I sometimes play that as well. I know in the near future I will have more time to play each of the games and know I will not be bored!
