What is still missing from the sims 4 base game? (If anything)

I think the best base game for the sims was found in Sims 2. It had so much Sims play packed in that base game. Sims 3 had a lot of play too in base game but I remember people complained about some things missing. Maybe the piano?

But Sims 4 was bereft of so much stuff in the base game it didn't hold my interest for very long. It is so much better now! I can play for hours and not want to shut it off.

Can it be improved in its gameplay? Always! I'm looking forward to what they will do next. I agree that better babies and more interaction within the sims is key. And yes, I miss vehicles too!
