How often do you create families and households that have multiple sims?

Never less then 8 for every house. I want pets so bad but no room ???

Was hoping for a poll but my answer is almost never. I usually start with one single sim.

That's mostly what I do B)!

When it comes to playable ones then rarely. Usually it's just 1-2 sims. Roommates happen or a combo of one sim with a cat/dog, sometimes I might create a single parent (notably my homeless challenge cuz it's just the right amount of obnoxious with a toddler in tow lol), but I almost never create families or even predetermined couples. I just enjoy it more when things happen organically in-game and can go to unexpected directions.

My very first sim for TS4 was a single male (pretty much a staple that I always start with one male sim). Later, because I just wanted to create a female sim too and couldn't be bothered to jump between two separate households, he got a roommate. I did not plan to hook them up, for some reason the roleplay ideas in my head didn't support this, but then he saved her from a housefire, she got the "awed by a life saving hero" sentiment while he felt "close after a close call" and it kinda went on from there. Also happened that I was planning for them to just get two kids but then on the supposed second one they got freaking triplets instead and ended up with 4 babies at once.
I love it when unplanned stuff like this happens and how the stories kinda write themselves. Sure, I do tend to have general ideas for each character but I'm very flexible when things "don't go as planned" and often embrace them.

I find starting off with 1-2 unrelated sim leaves things more open for me. I might want to emulate some type of scenario with multiple sims in the future. Too bad you can't actually make starting scenarios yourself because it could be interesting to start off with a bunch of sims who have different relationships than just the default. Now if you want to start with an e.g. dysfunctional family you pretty much have to then force that in-game after finishing up with CAS and I just don't really like the artificial feel of it.

I went through a phase of creating maxed out households, but my sim count soon reached max capacity ? now I have to make singletons to try and populate my game..

It’s just too easy and not much fun playing with a single sim.. I prefer the challenge of having a full house.

I don't really create Sims anymore. I have made some families and single Sims that I loved, but ever since my computer crashed and wiped out all my Sims I have lost the motivation to create Sims. I have recreated my Broke family from Sims 2 and I have a beloved mermaid that I made to look like Disney's Ariel. I open every save with my mermaid to place in Sulani and then I add my Broke family from Sims 2 and then switch to the premades and play on rotation.

I have families and households with a single sim, but they often have a pet.
