Speaking as someone who's playing Sims 3, I've noticed each expansion brings more stuff that I sincerely like to the game - each one seems better and more rounded than the first. Late Night outshines Ambitions, Ambitions outshone World Adventures, and Wold Adventures was really fun when it first came out.

Generations looks like it's going to be a really solid expansion - and seriously! All the age-appropriate gestures? SQUEEEE! I want to have my bad boy rise in the ranks of evil from his very toddler days, from impish gnat to dastardly supervillain! Or bad girl, for that matter. I wonder if its possible to seduce one of the strippers at your bachelor/ette party.
