What order did you get the sims in?

I didn't have all the packs for TS1 but soon as TS2 came out, I didn't even look and bought straight into it. Loved it. Stayed until TS3 and same thing, jumped right in and loved it. TS4... waited since TS3 had everything I needed, and TS4 was not even a full base game at launch. Now I play TS4 but am very selective about packs and ONLY buy on sales. TS2 and TS3 took all my money without a question asked.

I still jump back to TS3 fairly often, TS4 can't hold my attention the way the past games did. :/
