I play 80+ (?) households on rotation, so aging goes very slowly - sigh. A very few of the sims I created as young adults back in 2014 are still around as elders. So, I think 3 generations is about it for most households. In addition I love creating back stories, including creating their ancestors in CAS to have some family photos on the wall, and for my nobility houses I went back many generations. I love seeing sim kids grow up and try to develop their personality in a logical way, based on dna and how parents might influence their choices etc. Seeing how they look is so fun.
