I play two families and my darling plays three. Usually, one is enough for me but when the peeps get older, it may become VERY boring. So when one of the families has kids running around, the other one is in their middle fifties, and when they die I start a new generation... as soon as that generation starts, the one family gets older... so (sometimes with pausing one of them) i just try to keep one "old" and one "full of life" family at the same time.

With my woman it's the same, she also keeps it like this.
