This is a problem for me. I want to play them all, but I want to only play one household.
Usually this means having a house full of 8 sims and only moving anyone out because I want a kid and there's no room. When I'm forced to move someone out I'm torn between setting them up with a spouse or giving them a kid and OMG NO I WON'T CONSTANTLY BE THERE TO WATCH THEM, and I don't want anyone in my family dying where I can't pick up their gravestone and put it in the family cemetery.
I've started making smaller families just so that I can micromanage easier. You get ONE kid, that kid is the heir no matter if they're weird-looking, and if the heir dies somehow (unlikely, but possible), then whoever's left gets another kid.
It's pretend, so I can be a control freak if I want. o.o
