The Legacy Challenge Rules

This challenge sounds fun to me. I doubt I would take part in it but this is actually how I usually play The Sims just without rules. I enjoy starting out with a single member of poor circumstances and raise the family through generations. This time I was thinking about putting my character into context in The Sims 4 though and start out with a whole family, I'll see. I will take Crinrict's advice nevertheless to use "Save as" at least once a day. I've lost generations worth gameplay in The Sims 3 two times and it kills enthusiasm.
