Solar System Legacy Challenge

The Solar System Legacy Challenge is a ten-generation legacy challenge for The Sims 4, created by GinovaSims. Each generation is based on a planet in the solar system, including the Sun and Pluto, and comes with its own personality, story, goals, and required traits. The challenge is designed to be flexible, allowing players to adapt rules if they do not own certain packs.

General Rules

• Aging must be turned on, but you can set it to any length you wish. Long lifespan is recommended for more in-depth gameplay.
• Each goal must be met before the new heir takes over.
• You cannot give your Sims dramatic makeovers or personality adjustments. Slight changes to appearance are fine, but they cannot be made into a whole new Sim. Traits cannot be changed once they are given.
• No money cheats.
• The heir can be any gender and any sexuality.
• Children do not have to be genetic; they can be adopted, but they must be adopted as a baby or toddler.
• Mods and custom content can be used.
• Each generation offers three traits. The heir does not need all three, but they must have at least two of them.
• Updated rule: If you cannot add any of the required traits when the heir is a child, you may choose any similar trait and change it to the correct one when available (either as a teen or young adult). You can do this through cheats in CAS. The same rule applies: you must have at least two of the offered traits by the time the heir is a young adult.
• If you do not have all the packs required for a generation, either find a similar alternative or skip that rule. Where possible, you must complete each generation requirement.
• (Optional) Name each heir with the letter of their planet (e.g., Mercury = Max).
• (Optional) Use the hashtag #SolarSystemChallenge on posts and videos.

To Win: Complete all ten generations.

To Fail: Your current heir dies before the next heir becomes a teenager, or you fail to complete the goals in a generation.

Generation 1 – Mercury

You have always had a way with words and known how to woo others. You are known for your strong communication skills and are great with other people. You are not one to blend in, and always want to stand out – though you are not smug, just confident. Everyone wants to be your friend. You are an extrovert who truly cares for other people.

Traits: Outgoing, Family-Oriented, Self-Assured

Aspiration: Friend of the World

Requirements:

• Master the Charisma, Writing, and Parenting skills.
• Have at least one best friend and three close friends.
• See your friends at least once a week (the Get Together club system is beneficial but not essential).
• Never stay single for more than one Sim week (it does not have to be the same partner the whole time).
• Marry your soulmate before you become an Adult.
• Have at least two children, who you are very close with.
• Complete the Friend of the World aspiration.

Generation 2 – Venus

Your parents always spoiled you and your siblings – whatever you wanted, you got. Because of this, you have grown up always getting your own way. Everyone adores you for your good looks, but once they get to know you, they discover you are actually quite a shallow person. You cannot stay in relationships long-term, there is always something wrong with your partner, never you. Friends come and go, but you always have your parents and siblings to rely on.

Traits: Materialistic, Romantic, Self-Absorbed

Aspiration: Mansion Baron

Requirements:

• Have at least six romantic relationships throughout your life, but never stay with them for more than four Sim weeks.
• Have at least four children (the other parent can be the same or different).
• Have one or more of your siblings be your best friend.
• Never have any close friends, other than family, last more than a week.
• Visit your parents, or have your parents over, at least once a week.
• Never complete a career to level 10.
• Master the Photography skill.
• Complete the Mansion Baron aspiration.

Generation 3 – Earth

You are the middle child from a broken family, with only one parent who had to balance their time between you and all your siblings. Even though your family does love you, you never felt truly loved or seen. You are quite self-destructive because of this, and can never seem to let yourself be happy. There is still hope for things to turn around, but you must learn to love yourself before you can let anyone else love you again.

Traits: Gloomy, Loves Outdoors, Paranoid

Aspiration: Freelance Botanist

Requirements:

• Must be the middle child.
• Have at least three romantic relationships, all of which you break up with them (do not ask to be friends).
• Have at least three careers, but quit your job before you reach level five.
• Master the Wellness and Gardening skills, but not before you become an Adult.
• Complete the Freelance Botanist aspiration, but not before you become an Adult.
• Have only one child before reaching Adulthood.
• Never marry before becoming an Elder.

Generation 4 – Mars

Your parent never took good care of themselves, and their self-destruction often meant you had to be their emotional safety net. You were always there for them and looked after them, but as their child, they should have been the one looking after you. As you got older, you realised how terrible that had been for you. You never got to truly be a child. This has led you to become quite angry and frustrated, but you will not let yourself turn into your parent. You are passionate about fitness as it has become a cathartic way to let your aggression out.

Traits: Hot-Headed, Ambitious, Perfectionist

Aspiration: Bodybuilder (or Academic if you have Discover University)

Requirements:

• Have a close relationship with the previous heir growing up, but lose all friendship when you become a Young Adult.
• Visit the gym at least once a week throughout your Young Adult and Adult life.
• Have a part-time job as a teen.
• Graduate high school with an A grade.
• Get at least an A grade at university (if you have Discover University).
• Reach level ten of any career.
• Never have a serious relationship until you are at least level eight of your career.
• Rekindle the friendship with the previous heir only after you reach level ten of your career and are engaged to your fiancé.
• Have at least one child.
• Master the Fitness and Research & Debate skills.

Generation 5 – Jupiter

You were quite fortunate in your upbringing. Your parents established themselves and their careers before they had you, which meant you were quite well-off. But they did not spoil you — they taught you to work hard for what you want. They gave you the opportunity to explore different hobbies and skills, and were supportive of whatever you wanted to do. You take full advantage of this. Any opportunity that comes your way, you take it. You can never settle on one passion and have many different interests. Because of this, you are quite a well-rounded person with skills in many areas.

Traits: Adventurous, Self-Assured, Cheerful

Aspiration: Nerd Brain (or Extreme Sports Enthusiast if you have Snowy Escape)

Requirements:

• Live in at least two different worlds as a Young Adult, and another two different worlds as an Adult.
• Master the Cooking, Painting, Rocket Science, DJ Mixing, and Bowling skills.
• Travel to Sixam.
• Master at least one instrument.
• Master at least one extreme sport (if you have Snowy Escape).
• Complete your aspiration before you become an Elder.
• Have at least two children before you become an Adult.

Generation 6 – Saturn

You were always moving around growing up, from house to house and world to world. This has meant you are quite well-rounded and intellectual due to your understanding of different cultures. Your wisdom means a lot of people look up to you and rely on you, but you can be known to sometimes look down on others if they do not quite match your intellectual standard. You can be quite cynical and pessimistic, but you are just being honest and real with yourself and others.

Traits: Genius, Gloomy, Bookworm

Aspiration: Renaissance Sim

Requirements:

• Master the Selvadoradian Culture, Vampire Lore, Writing, and Logic skills.
• Visit the library at least once a week to work on writing books.
• Write and publish at least five books before you become an Adult.
• Get at least an A grade at university (if you have Discover University).
• Reach level ten of the Education career (if you have Discover University).
• If you do not have Discover University, reach level ten of the Writer career.
• Visit Selvadorada at least twice as a Young Adult (if you have Jungle Adventure).
• Have three children with your long-term partner.

Generation 7 – Uranus

Growing up with a parent as intellectual as yours, you have always been exposed to exciting and different things. Your brain never settles and you always want to be trying something new. Because of this, you can sometimes be seen as a bit eclectic and erratic. But there is nothing wrong with that, especially if it means your exposure to new things can enlighten your mind and life.

Traits: Erratic, Non-Committal, Genius

Aspiration: Computer Whiz

Requirements:

• Reach level ten of the Science career (if you do not have Get to Work, then Tech Guru career).
• Reach level five of at least ten skills over your Young Adult life, but focus on one at a time.
• Master the Painting and Programming skills.
• Do not have any relationship last for more than two weeks.
• Have a Cowplant at all times throughout your Adult life.
• Complete at least one collection of your choosing.
• Have only one child.
• Complete at least two aspirations, one of which must be the Computer Whiz aspiration.

Generation 8 – Neptune

Your parent’s eclectic ways meant you grew up quite free-spirited and exposed to new ideas. Though you were more of a person of fate than your parent, who was a person of science. You were more spiritual, and they were more factual. This causes a lot of tension between the two of you, though you do still get along — you are just two very different people. Since moving away from home, you try to connect more with your mind and soul than the outside world.

Traits: Creative, Child of the Ocean, Goofball

Aspiration: Painter Extraordinaire and Musical Genius

Requirements:

• You must move to a new world when you become a Young Adult (if you have Island Living, move to Sulani).
• Master the Wellness, Painting, Medium, and Guitar skills.
• Do not have a relationship last for more than a week until you have mastered these skills.
• Sell at least two paintings a week.
• Have five children; the other parent does not need to be the same person.
• Complete the Painter Extraordinaire and Musical Genius aspirations.
• Clean Sulani (if you have Island Living).
• Befriend Guidry (if you have Paranormal).
• Hold a séance at least once a week (if you have Paranormal).

Generation 9 – Pluto

You are the youngest child of a big family and often feel overshadowed by your older siblings. They always seemed to do better than you growing up, and you never really stood out. This has caused you to feel a bit like the black sheep of the family. Because of this, you never really connected with your siblings or parents. You never really do much with your time, as you feel it would not be good enough anyway — but no one knows your real passion, or what you are really good at.

Traits: Loner, Gloomy, Jealous

Aspiration: Soulmate

Requirements:

• Lose all positive relationships with your parents and siblings as a Young Adult.
• Never achieve more than a B level at school.
• Only ever have part-time jobs or freelance work as a Young Adult.
• Master the Video Gaming and Mischief skills before you become an Adult.
• Have a midlife crisis when you become an Adult and discover a new passion. This can be any skill you wish, but you must master it before you become an Elder.
• Only ever get a full-time job as an Adult, and reach level ten before you become an Elder.
• Never have a romantic relationship or any close friends until you are an Adult.
• Meet your soulmate as an Adult.
• Have at least one child.
• Reconcile and make amends with your siblings (and parents if they are still alive) when you are married and have your first child.

Generation 10 – Sun

You heard how much your parent suffered before they truly learned to love themselves and others, so you know how important self-love is. You believe that core energy comes from within and that you are the only person who can truly make yourself happy. If you want something, you will work until you get it, as you believe you are capable of anything. You are not really interested in romantic love, but are passionate about your friends and family.

Traits: Cheerful, Good, Self-Assured

Aspiration: Party Animal (or Leader of the Pack if you have Get Together)

Requirements:

• Never have a romantic relationship.
• Have at least five close friends who you see at least once a week (the Get Together club system is beneficial but not essential).
• Visit your parents, or have your parents over, at least once a week.
• Live with at least two friends throughout your entire Young Adult life, either through the Discover University roommate system or in your household.
• When your parents become Elders, they must move in with you.
