1. My rotation is sheer chaos. I do what I want, when I want. However, I limit Sims to doing only things I think they would naturally do. For example, it took a long time for me to see the magic realm, because a Sim had to naturally find it by doing things I thought were within that Sim’s character. Sometimes I set a specific rule for a specific Sim or household. I do try to rotate when Sims are sleeping, because I got tired of Sims being “late for work” when I rotated to a new household.
2. I have about 250 played characters, after some painful self-culling. They are a little of everything, but probably 2/3 single. I have 10 or 12 families now that are related either directly or through marriage. I started with one Sim, who got married, then I added his parents, grandparents, and cousin. My Sim had five children, and the cousin was created with three children. The cousin married a Sim, and I gave that Sim a brother and parents. My main Sim also has extended family of a grandmother and seven grandchildren. Then I added my main Sim’s wife’s parents and brothers. My game keeps growing like this. But I also play single Sim households with no family at all.
3. Sometimes I play the same family for a month, or sometimes just an hour. I rotate freely. I may play one household over and over, while I play another household only once every six months. It always holds my interest this way. This is the same save I started in 2015.
4. I love Newcrest because it is such a blank slate, but I edit all the worlds. I play in all the worlds. I rarely play in Selvadorada or Granite Falls because I can’t get the residential mod to work. Most of my play ends up happening in Strangerville and Willow Creek, but all of the worlds are involved.
5. Rotational play is hard to coordinate with acting gigs and college classes. I usually play one household for at least a Sim week when dealing with those matters. Otherwise, rotational play is ideal and the only way I personally want to play.
6. I like it all! I have families, singles, humans, mermaids, vampires, aliens, and pets. I have Sims who started as babies and Sims who started as elders. It just depends on my mood.
