Yes! With hula zombies when they die of old age!
Because in The Sims 2 when an Elder where granted a gilded gravestone there was a sence of fulfillement that is absent on the Sims 4. After all, what is the use of completing collections and aspirations is the Sims is just going to be deleted by the game in the end, with nothing special left behind?
It could come with a Hall of Fame for Sims (nothing too heavy or complicated) just a record with the Sims portrait and his/her/their achievements. And maybe a little text entry done by the player with perhaps a little Bio that will allows us to treasure our Sims without shortening the lives of the save files.
