I think I will still be rotating. I'll add 1-2 SE Asian households to my rotation. I think one of those will be the Bun Ma house. A friend of mine grew up in a very similar household from the same culture, so it will be interesting. I also think I'll explore the horses & horse ranch pack more.
Some households in my giant rotation may shift to being renters and I may prioritize some favorites as my main gameplay households with the others as awesome neighbors with Neighborhood Stories. I like the ability to be flexible though. I'm also sure that I'll do some building and that my Sims will travel a lot because they do. I replay the travel worlds a lot with new sims or with sims revisiting places at different stages of life.
