For me its when I find the right house for my sims. I started my legacy in Windenburg, and while two members of the second generation live there, the second generation heir lives in NewCrest in a house I built. The third generation heir lives in a penthouse in San Myshuno, and I play all three lots as I love them all equally. The original home in Windenburg has tons of family photos and lots of personal touches. I have pretty much followed what I did in that house with pictures and the other two homes also have tons of family pictures to make the lot feel like home. The fourth generation heir is part of the San Myshuno household and she'll stay in the Penthouse. I have spent a lot of time having all the lots plumbing upgraded by my sims, and to change up the lots I just go in build mode and change the walls if needed, or I go into buy mode and change the color swatch on the bed so that it feels new and fresh.
