@EeveeTinn I play a rotational game. I started with a Sim that I created in the likeness of one of my ancestors. But I already started this in The Sims 3. So when The Sims 4 came out I recreated him and his Sister. And started off from there again. (When I feel like it, I still do some searching for my ancestors with some lineages I reached to 1450 AD)
I played with this Sim for a while together with his sister. Then I wanted to create their parents but the game wouldn't let me so I ended up creating a brother instead. The Sim I created first I maxed him out on all the skills and made him a real patriarch. He also had almost all the jobs you can find in every pack and, in fact, he must be over several hundred years by now. He only married NPC's which of course became Player Controlled Sims. And had several sons and daughters more than 15 in total. He divorced more times than a regular moviestar an remarried. He also had a couple daughters with alien inseminators< which with some inventive use of a mod I lured into the world. Most of his children are still alive and are married.And most of them also maxed out on their skills and aspirations, some of them happily live for ever after. Some of them died because, I did not want to keep them alive or I did not want to keep playing with them.
At a certain moment I stopped the ageing processes because, I still wanted to make a hugh family tree and also play with the offspring. At this moment I play with over 135 Sims but I do have my favorites.
To prevent family marrying family I had to create another two extra families and have them branch out as well. These families live in all the worlds and are the famous bunch. Also, like @SheriGR, I love to let them garden, I have a family of vets, movie stars, scientists, gamers and medical staf. Practically every job you can find in the packs I play with my sims. And now with the new EP I want to experience the new Jobs too. So you see, there are so many ways to make a nice story. You will definitely find yours.
Have fun playing. 😉
