Dear Sims,
i have read some of the comments above but not all, thank you, that you do that. I love the game a lot and still enjoy a lot of game-play.
One thing i did not read about is an additional young-elderly Life-stage would enhance Generation-game-play a lot. As, if i play without any Potions/other ways to make a sim younger, he will normally not to be alive to see his grandchildren. Its also a life stage, were few health issues come and no more pregnancies arise but many Sims may want to carry on to work. (Like 50-70 years) in real age. With that addition it should be possible to have a natural lifecycle within a family with some time for grandparents.
have a great day!
