The royalty challenge

Main Objectives
Repopulate your whole sims world within 10 generations (That also could mean less), with only descendants of the original family, Collect all the collectables, and do not have any members of the main family die unless it is of old age.

About
In this challenge, you play as a three person family -- A king, A queen, and A princess. They are the rulers of your Sims world and are allotted the Biggest lot and a huge mansion, plus infinite money. Their plan is to take over the world, and collect all of it's wonders. Each position in the house has a job to do, and as the sims grow older, their positions will shift. 
Starting Out​

Create a Sim --​

King: Must have the Collecting aspiration, and the "Loves the outdoors" Trait. His first name should be king, and his last whatever you want it. Also, he should be a young adult
Queen: Must have the Successful Family Lineage aspiration, and the Romance trait. Her first name should be Queen, and the last name, whatever you want it to be. To make it more challenging, you should give them both the "Loves Family" trait, so that when the queen has other relationships there may be problems. The queen must also be a young adult.
Princess: Must be created using the DNA tool in CAS and must remain a child. Her name should be princess, and her last name, whatever you want. For the first child, you should randomise the trait and aspiration.

Home, Lot and Town --​

Home and Lot: The home should be placed on the biggest lot in town, and built to house 8 people in separate bedrooms as it is a castle. It should also have spaces for skill building, exercise, entertainment, collection storage, and a place to keep a cow plant or two. The King, Queen, and Princess' rooms should all be extravagantly decorated, while the rest can be plain.
Town: Though you are allowed to stick to randomly generated sims, it would be much more interesting to fill the town completely with gallery sims. It is up to you. But ever single house, even the starters, must be filled.

Gameplay
Jobs --​

King: The king's job is to collect. He is the only one allowed to go out and collect any collectables in the game. He cannot have a job and the only skill and aspiration mastery done by this sim must be one that pertains to collecting (ie. fishing). The first king must find a cow plant berry as his first item. In addition, he is the one that will be doing the cleaning and repairing in the house when there is no other non-pure blooded children/families in the house.
Queen: The queen's job is to have babies with all the men in the town. These children are not pure blooded, and are known as nobles. Once the queen has slept with all the household's men, she can invite them to come live with the family and feed them to her cow plant one by one. Then, once their children have aged to young adults, you can place them in that household. The queen also must tend to the garden and is the only one allowed to interact with the cow plants. She also does most of the cooking and cannot have a real job.
Princess: 

• Child: As a child, the princess' goal is to master her childhood aspiration and get one skill to level four. She will not attend school.
• Teen: Her goal now is to get one Skill to level seven, and to successfully find her prince charming who will become the next king. She is still not allowed to attend school.

Nobles: The nobles jobs are to keep the house clean and cook when the King and Queen cannot. They should go to school as well.

Ageing --​

Child Princess --> Teen Princess: You can age her up immediately as a baby (Because babies are pretty useless in the Sims 4 XP ). A child princess can only age up into a teen once her Job is done. AKA: Finishing her Aspiration, and reaching level four of a skill.
Teen Princess --> Queen: A Teen Princess can age up into an adult once she has reached level 7 in a skill and has become the girlfriend of the one she wants to be her King. Once she has aged up, you can move in the future king and age him up as well. Once Married, They will become the King and Queen and take on those responsibilities.
King & Queen: The queen and king age up with their princess. I.E. When the Child turns into a teen, they turn into adults. When the teen turns into an adult, they become elders, and when she is married they must move out of the house.
Nobles: The children that the Queen has out of wedlock can immediately be turned into children. They can only be aged up when they have reached their A Grade in school. Once they are young adults they should be moved into their other parent's home.

Heirs --
When the Princess and her prince have aged up to become King and Queen, they must first have an heir before the Queen can start having children with others. The Princess must be the first female born into the family. If you have boys before a girl or if you happen to have twins or triplets, they will be treated as a Noble.
