The Sims 3 Forever Young Founder Challenge

For those of you that are getting tired of the Legacy Challenge I created something more exciting: The Forever Young Founder Challenge. 
This is just like the Legacy Challenge but more difficult : 
Rules 
1. The Founder Family must have 20 generations. 

2.All the members of the family must have one common trait (including the one they marry). You can create a sim and put in the town so you make sure someone will have that trait. Each sim must have at least one bad trait including the founder. 

3.The Founder must live all throught the 20 generations as a ghost or you can use the potions from the alchemy set or/and the chemistry set.But he/she MUST live. 

4.The family must live on a 50x50 lot and start with $1,000 . (If you want to make things more exciting you can start with 0). 

5.The founder must not move away from the lot. But the others can when they get to young adults. 

6.All toddlers must be learned how to talk,walk and potty train . 

7.The Casino may only be used once every summer on the day before Leasure Day. Otherwise its off limits. 

8.All premium content items must be unlocked in orther to use them. To unlock a premiun content item your sim has to get to level 10 in his carrer , master 1 skill and have 4 friends. 

9.On Spooky Day all children and teens must go trick or treating and must carve one pumpkin. 

10.In the winter the family must have at least 1 gift giving party and 1 feast party. 

11.As I said you can move the young adults out but each generations you have to keep one sim that will continue the legacy.The Founder will only give birth to the first generation. 

12.If a sim that was in your family dies, even though you moved them out you have to get their grave into your lot. 

13.No supernaturals. But they can learn the alchemy skill. 

14.No cheats except the familyfunds(family name) 1000 you use at the beggining of the game. 

15.By the end of the challenge your founder sim must have mastered at least 10 skills and have 5 carrers up to lvl 10 . 

16.Once you get to the 20th generation you have to play until each sim dies.(You can't marry or have babys). 

It's not a lot of rules most of them are just gonna come by themselves. It's not as easy as The Legacy Challenge but not that hard either. 

Happy Simming. P.S.:You can use whatever town you want but they must live in a 50x50 lot.
