I have oodles of families, but only really play the ones that excite me. And then, sometimes years later, I'll go back and say, "HEY! I kinda sorta remember these guys. I think I'll play with them for a while," and the next thing you know, I'm sucked in. This makes it hard to keep up with my POSTED stories, since I have a very hard time playing without stopping to write stuff (I have a rather observational play style, rather than planned and plotted story-telling), so I have oodles of PowerPoints going.
It all depends on my mood.
I'm really into Sims 2, because I LOVE the flavor of it, and also, when I switched to a Mac, I went years without it, and missed it soooooooo much, that I went to great lengths to get it working on my Mac, and then, finally, bought a Windows laptop specifically for playing games I could not play on Mac, but had missed over the years. Lord of the Realms, Tropico, and the like. I like old games.
Also, Sims 3 has never been very stable for me, so although I do love it (and particularly love World Adventures - it sucks me in like crazy!), I wind up switching back to Sims 2, because of frustration and game crashes. But I do love it so much that I keep going back and braving the game crashes, so... It's kinda pathetic, really.
I've never been able to get Sims 4 to actually WORK on either of my computers, though. Oh, sure, it will load, and I can create a sim, and build a house (it takes forEVER, because of lag issues), and then I can watch them take an hour to get their meal from the grill to their mouths. Not an hour to eat. An hour to get the plate of hot dogs off the grill and the first fork-full to their mouths. Then they have to take another hour to eat. And two hours to pee. Don't even get me started on showers. They have no time to do anything other than basic survival. Since other players manage to make their sims actually DO things, I have to conclude that this is not normal, and it's just my computers. BOTH of my computers. So, if I'm ever rich and famous, and can afford a really zippy-woo computer, I may try Sims 4 again. There's a lot of cool stuff out there. I'm particularly interested in the vampires and TODDLERS! HOORAY! I still can't believe that it took this long for EAxis to put in something that should have been base game, in the first place.
