Complete-Game Worlds without any CC?

Try here, I'm sure she uses no CC and has various versions of her worlds. https://my-sim-realty.blogspot.com/search/label/Worlds

Thanks I will take a look at those worlds! If other people have suggestions too please feel free to post them!

I use this site often to find worlds. It has a sort by CC free option: sims3.thesimscatalog.com/sims3/?filter_custom-content=cc-free

*Edit: Quailhogs has created some incredible worlds that don't use CC. They have also created some interesting characters for those worlds.

And rflong7 is a prolific and creative world builder that has many different types of worlds ready to go.

I don't think this blog is active anymore, but it's still up and I know has a at least 1 or maybe even 2 worlds that are cc free:

And over at MATY, Anach has a download link available for Expanded Sunset Valley made with 0 CC and 0 Store content (scroll down in the thread a bit to find the link):

The official Sims 3 Exchange also has quite a few worlds that are CC free, believe it or not.
