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 on occasion, I enjoy playing challenges, and sometimes I am an ant farm player and just let my Sims do their thing and then develop my story around the consequences. I also in some saves rotate households. It all kind of just depends on my mood.
