What’s a gameplay feature you’ve NEVER used? New ideas to spice up your game!

I started a Super Sim save and started to make a list of all the things to do with her and realized how much I have not done yet:
Veterinarian/owning a vet clinic.
Exploring the ruins (I went in one and then left, never even got below the first level).
Roomba-style vacuum.
Critic career.
Just got Island Living, so everything with it.
Cop Career.
Making a clone.
Getting pregnant by alien abduction.

And many more!

It makes me realize how much I stick to specific storylines. I want to branch out and explore more things.
