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.
I voted for rotational as that is what I mainly play (95% of the time) - although there is the odd time I build, play legacy style (or challenges) or create Sims - it is very rare.
I like to build and make sims and I've played my simself in rotation which I ended up preferring, I really only turn off free will when I'm trying to get a picture or even when I need to kill a sim a certain way and can't have them running off lol. I have tried some challenges too sometimes I'll do this all at once and keep multiple saves.
Mine could be considered a combination too I guess. I play only one house at a time, and micromanage everyone in it. I like to play one Sim for each generation. As soon as my chosen heir ages up to ya, I turn aging off and play just that Sim until I feel it’s time to start the next generation.
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.
Building is all I really ever do. The only time I enter CaS is to create a sim to run a playtest on my builds. I just cannot enjoy playing families and stories for generations.
I honestly look at some of the threads about legacy challenges and generational/rotational play and just sit dumbfounded about how people can suffer through it xd
