THE PERFECT CREATE A SIM (CAS) WOULD BE:

I would like to be able to set favorites and preferences in CAS, instead of having to interact with something in game to do so or having it randomly assigned. And that when they got to a bar they'd order their assigned favorite drink, when they autonomously cook they'd default to their favorite dish, etc. As it is, choosing their preferred weather is pretty easy, but choosing a favorite movie genre requires watching and liking a movie of that genre first before you can make them tell another sim that's their favorite. Drinks are randomly assigned and food doesn't come up at all. And I don't know of a way to choose a book or music genre.
