What is your favorite thing to do in the game? and what packs help that?

My favourite thing is to, starting from nothing, go all the way to the top of a (exciting) career, while building my dream home bit by bit with the money I make (you know, like, something that will never happen IRL ^^). So I really enjoy Get to Work for the ability to accompany my Sim to work and having a real hand in their performance.
