Alright, I freaked out again.  And this time uninstalled the Sims 3 and reinstalled the Sims 2.  I am never going back!
I have started the Royal Kingdom Challenge (entirely from memory).  I currently have 6 families.
1st is the Royal couple, King Alric & Queen Anne Bronin.  They had 6 children before the Queen died in childbed.  Only 4 of the children reached adulthood (Princess Anne, Princess Orella "Ella", Prince Albert, and Prince Magnus)
2nd is the noble Cromwell family, Earl Zachary & Lady Arabella.  They had 6 children also before Lady Arabella died in childbed.  4 of their children reached adulthood (Lady Constance, Lord Viktor, Lord Hektor, and Lady Clarissa)
3rd is the noble Danneville family, Earl Walter & Lady Sarah.  They had 9 children before Lady Sarah died in childbed.  6 of their children reached adulthood (Lady Godiva, Lord Ragnar, Lord Archibold, twins Lord Hagan & Lord Henry, and Lady Floria)
4th is the peasant Brown family, John & Margaret.  John and Margaret are farmers who welcomed only one child before Margaret died in childbed. John married another Margaret, Margaret Joynes.  They had a daughter also named Margaret.  He married again to Carolyn "Caryl" Zarubin.  They had no living children and Caryl died giving birth.  John then married Trista Shaw.  They currently have 1 child a son named Saul.  This means John has 3 living children: Solomon, Margaret, and Saul.
5th is the peasant Smith family, Aiden & Catherine.  Aiden and Catherine are also farmers who had 2 daughters (Christiana & Adela) together before Catherine's death.  Aiden then married Jane who gave him 4 healthy daughters (Alis, Elaisse, Lynne, and Kinna) before her death.  By this time Aiden's eldest daughter Christiana had reached sexual maturity and was carrying her father's child.  Aiden married young Christiana and they welcomed another daughter (Catherine).  Christiana died giving birth to her 4th child (Catherine is the only who survived infancy).  Aiden then seized the opportunity to marry is next eldest daughter Adela who was already heavily pregnant with a bastard child whose paternity was unknown.  Adela died in childbirth along with her baby daughter.  Aiden is now an elder and barred from marrying a childbearing woman.  He has 3 surviving children (Elaisse, Lynne, and Catherine)
6th is the peasant Strong family, Joseph & Lia.  Joseph and Lia are farmers who welcomed only one child before Lia died in childbirth.  Joseph then married ?  She died before baring any living children.  Joseph then married his 1st wife's cousin, Mary.  Joseph and Mary had twins, Malice & Mary, who took their mother's life at birth.

 
Alright.  I just went crazy on New Years Day and uninstalled the Sims 2 (bye-bye Test of Time Challenge and all my simmies) and bought and installed Sims 3!!

Been having graphics card issues since then.  My laptop apparently can't really run Sims 3 unless its on the lowest settings.  But it took 2 corrupted game files to figure that out.  So I am on my 3rd Sims 3 challenge now.

I tried the Perfect Genetics/The Clan challenge 1st.  Where you make a guy with very distinct skin and hair coloring and you have him marry and have children until he has a perfect heir.  Do this for 10 generations.  Its pretty hard.  It took 8 children and two wives to get my perfect heir.  My heir had given birth to one non-heir child before the game file was corrupted.  The End.

I tried the Alien Rainbow Challenge next.  You have a Cassanova type also with unique skin coloring.  He or She is supposed to have 10 children with random lovers.  Once the 10 children are getting to adult or young adult stage, you create a new CAS male (or female, whichever gender you started with) with another unique skin tone (different from the 1st) and that man breeds with the daughters of the previous alien.  All the while I suppose the sons of previous alien are just living their lives and spreading those colorful genes randomly with normal story progression enabled.  After 10 children are born of the newer alien and the daughters, you create another differently colored alien man  to breed with the new daughters.  The aliens only breed with the daughters of the alien unions (no townies after the 1st alien) and a new color alien each time until you've run out of colors and must start repeating.  The challenge ends when their are no daughters (or sons if you started with a female alien) born of the 10 allowed children.  I began my challenge with a pink alien named Jesse Pinkman (named for character from Breaking Bad).  He accidently had 13 children cuz he just knocked them all up at the relatively same time so the 3 sets of twins put him over the 10 children allowance.  His replacement alien was Leaf Greene who had 10 children including triplets.  The 3rd alien was River Sky, who never bred cuz I lost that neighborhood file.

Now I am on the Legacy Challenge.  And have experienced the most disappointment I can ever remember with a sim. My beautiful young daughter became unexpectedly pregnant during her teen years.  I left her house to check on the progress of all of her moved out older brothers and just watched in horror as the notifications about her started flowing.  My family is Starry Drem and her husband Land Gwydd.  They have 4 children: Lywlynn, Brendyn, Wyndym, and Gwendolyn.  Brendyn's imaginary friend is also kind of their child and is currently engaged to Gwendolyn.  Each child has one kid right now.  The grandkids are Starry Brooke Gwydd-Drem, Laury Gwydd-Drem, Isaac Lang Drem-Sargent, and Geoffrey Gwydd-Drem.
