Sorry to double post, but let's see if I get the theme of this challenge right. So, I start out (let's imagine) with Agnes Crumplebottom, within the first ten days she marries Christopher Steel, then gives birth to a baby boy. Weeks pass and the kid is already an Adult, completed all the moving requirements (if), then, he moves to an empty house (or a townie house - I didn't get this right), and then has to find a wife, have a child etc.. The challenge concludes when the tenth generation of this Sim has completed all the moving requirements, right?
