Best expansion pack based on it's world?

@Chaotic_Moira This conversation has given me something to think about. Since I made that post explaining how I see the Sims world I've been thinking about how I got to that view. It all started with Willow Creek and comparing it to New Orleans. It didn't really start spreading to the other worlds until about a year ago. I've been giving this some thought over the last couple of hours and while I'm getting ready for work. Now I'm seeing how I'm limiting my storytelling by having such a restrictive view. And how I'm dragging the real world into my little escapist world. I owe you a big thank you for giving me something to think about. I used to have a much broader view and more expansive stories and I've gotten away from that.
