Story Progression? Pfft. Okay...I'm boring, and have always tried out a femme fatale in every Sims incarnation as a first family. Gave her all the traits, played for a bit and then left her alone whilst living real life. BF tries his hand out at the game, makes a thief and plays for several days.
Eventually I get play and 'lo behold my femme fatale has adopted a child. WTF? For a commitment phobic, flirty, mean, lucky socialite to ring up and actually want a child is so unbelievably unrealistic it was criminal.  Plus I don't really like the idea of something so major to be left to half cooked AI. Give me the big decisions and continue with the banality of the game please (i.e skill building, meeting friends, etc).

I thought that maybe she shagged some random without protection, but the baby had NO father present in family tree. Strange. Needless to say, entire family was nuked. Urgh why can't they get the game right!??!
