I've been playing Sims games since Sim City originally came out, and my aunt had it on her computer. My family didn't even own a computer until 1996, but the games we had were predominantly Maxis Sim games. (I loved the trial version of SimCity 2000, where you played for 25 minutes and then random disasters destroyed your town) I have all the content for The Sims and The Sims 2, and most of The Sims 3. but The Sims 4 came out around the same time I had my first child, and I didn't have time to play anything, plus I was severely disappointed in the lack of content in the base game, and my computer wasn't very good.
But now I have more time to play, and a brand new gaming laptop, and I'm still finding new things that were added to the base game in the last 6 years. If the game had as much content when it came out as it does now, I'd probably have made more of an effort to continue playing it. I don't believe for a second that it's aimed at teenage girls though. I used to know several men who played, but they all stopped at about the same time I did, and for the same reason. The base game was a hollow shell of the previous games. But if they are playing Animal Crossing and Stardew Valley instead, I don't think it would be that difficult for them to return. Especially with all the unique new ways to kill sims now. >:)
