Researching this on the internet was very difficult, and I ended up without the answer I’m looking for. I am trying to find out whether it is possible to create a new household once I have started playing in a town with two already created households. I am asking as I wouldn’t want to start all over again in case I am required to make all households I want to, before playing in the town.
You can still create new households from the neighborhood screen, at any point of time in a game worlds existence
So I created a new world as a test for this, with heavy use of randomization.
Meet Emanuel Bush, he's a funny bro who wants to tell jokes. He's just been moved into
a shack an amazing new home.
Going back to the world screen, I made sure to save my
horrendous lovely cheap starter house.
I noticed that he was all alone, and may get lonely without neighbors.
So, I created a new household to move in.
With a bit more random button clicks, welcome another bro, Amber Ruffin, to the neighborhood. She has a nice home next door imported from the gallery.
Life was well and all were happy. But what's a good sims story without an evil person? After letting Emanuel and Amber chat for a while, I decided another house was needed. I saved and exited to worlds and created a new household.
Margarita Knutson. She is the bane of the neighborhood. Being a public enemy, hot headed, evil, kleptomaniac. She's here to ruin peoples day.
And she's already off to a great start in the neighborhood.
So yes, it is definitely possible to create new sims at any point in time to suit your needs. It can be a great plot development for new sims to move into the neighborhood.
Another neat feature is you can evict households to add background sims, so creating a household, moving them in, and evicting them, but they will still roam that world every so often.
