Until I tried the Immortal Dynasty Challenge, I was doing a lot of re-starts, and never went past a couple of generations.
I tend to get quite attached to my Sims, and usually play with aging turned off. At some point, they would start having kids, but then I needed to turn on aging so the kids could grow up. I did play one couple to elder status, but then one of their kids got married, and I chose to move the new spouse into their existing family home, making a total of 5. If I had continued to play that family (and keep the elders on Ambrosia), the other kid could have gotten married, and each of those couples could have had 1 child, then the household would have had 8 members. At some point, I would have needed to let some of them go - by either letting them die off or moving them out (and on the consoles, they disappear from the game).
Doing the dynasty run made a big difference in my gameplay - I've learned to accept visits from Grimmy.
I'm still not too keen on what the designers did to elders. The reality is that an elderly person who keeps physically fit - like one who has SuperMaxed athletic skill - should still have a decent, well-muscled figure/physique and good posture. They've done a lot with body type design in CAS, and I'd like my elders to look healthier and more robust than they do, especially if they are physically fit.
