Quick Question on Life cycle for sims?

So, I've gotten to the stage of my town where Sims are beginning to get old and starting to die. I have had jobs for the Ghost Hunting profession where I have had to banish ghosts, and families are no longer living at the home I'm scanning or searching.

MY main family I used the the potion of life/freeze [whatever it's called] to keep them as an adult and have begun playing the children, as I wanted to keep the start of the generation alive to see how it would pan out. So they will stay alive unless, an accident happens etc.

I'm wondering to whether the game handles 'new' Sims being implemented into houses and keeps the cycle going or will I have to keep creating and randomizing families to play alongside my family/families as they expand as well? I would have assumed that new families would be generated and move in to keep the game flowing, however I'm not seeing it?

Should I begin the creation of new families or will the game do this for me?

Hey,

Thanks for the reply, Just had a quick look through both of the linked mods/hacks and both look quite interesting, with awesomemod confusing the hell outta me at first sight. Think I might give a NRAAS StoryProgression a shot as I know a little about how it works already and seems I only need story progression to work properly.

I was starting to worry as my now somewhat empty Sunset Valley has around 10 families left with A LOT of empty households. I know supernatural has just kicked in but I wasn't after a ghost town!
