Thanks for the input, Rose. One of my first Sim friends, Simslover163 who is also a Facebook friend likes the idea, too so that's what I'm going to do. I'll move after my next visits in my game rotations and make sure I save their house and household as they are now so it will be more like a continuation of their story but in the new save,
It would be kind of like a parallel universe of sorts. I hope to put most of them in the same worlds that they are now in unless any overlap then the household would go into a different world fit my not-set-in-stone, one household per world. I think the Sims 4 scenario, 'Aliens Stole My Parents would a good way to begin that game save. Would keep the orphans in their original game saves if they were adopted my one my original households, though.
Thanks for letting me brainstorm with you. Now it's time to finish the back story I started earlier for Eugi and Giovannia that I'm writing in the first person with Giovannia telling her story. Guess I got my scenario household mixed up. They were actually for the Surviving the Holidays scenario where two Sims start out living together as enemies but over time slowly become friends and perhaps lovers. Hope you'll enjoy their story when I finish with it.
Have a great night!
