Is The Sims too childish now? Teen & Adult players have been forgotten

To be fair, they haven't put in much of any story line in, drama or happy.

There's a bit of something there going on with Johnny Zest and the Landgraabs (secret adult child?) and the Pancakes have some issues and weirdness going on with them. It's not as much or as clear cut as past games, but they've included a tiny bit. I can't remember the name of the family, but I think there's one that came with Get Together that has a suspicious death tied to it.
