Let me see, now. I create my own Sims in CAS; I use full-autonomy on, mostly so I can concentrate on my 'Target' Sim to achieve the skills for that Sims' future career. I like to play large families and this just makes it a tad easier to manage them. I will employ the Pause button to set up activities for certain Sims to help them achieve, too, not just my Target.
I'm also fond of building the house the family will live in, as mostly the premade houses are too squishy in size for me. I like to be able to zoom the camera in and see what I'm looking at. ;)
I also employ MCCC when needed. I have fun.
