Are there any worlds you never use?

I don't remember the last time I used Glimmer Brook, I will have someone go to the bar every once in a blue moon. But even when I make a spell caster (rarely) I don't have them live in Glimmer Brook. I also don't use Newcrest very often, I'm not a huge builder and sense it's empty I don't like moving my sims there. But I will occasionally use it as a place to put random lots that I need for gameplay, like a fake hospital (because I don't actually have get to work but for the story I was telling I needed one) a grave yard, ect.
