I'm always curious about how other people play, and I haven't seen a poll quite like this. I myself would have to choose option 8 because I play an ISBI-type challenge with several families.
I like to build, to create sims and their stories, and to micromanage them to attain certain goals, but also sometimes just to play their stories. I also often play several households in a same game save. So I guess a combination of options 1(cas), 2 (build), 4(autonomy off), 6 (challenges) and 7(rotation). Now that I think of it, there are often several sims in my households that I never play and I just let them with full autonomy, especially the kids. So I guess option 5 as well.
