I suppose the closest I come to what you described is that I play a full household, most of the time, which requires autonomy be on. I will then primarily focus on my 'main' Sim, if you will, and pretty much allow the rest of the household to do their own thing. Once in a great while, I'll intervene, (unless I've got students and Uni and then I direct their days so that they graduate Summa Coom Laude, all A's, highest distinction). The main character is my would-be celebrity Sim. I've played this same family in several iterations. Sometimes I've had to start all over due to a corrupted file, or Operator Malfunction (me goofing things up a bit). But, recently, with the patches playing havoc and not wishing to sit on my hands not playing until the mods I use are given the all-clear or are updated, I have taken to starting this family again in a TEST SAVE.
