I decided now that I would keep a family tree as Sims 4 does not have one now and I would soon be forgetting the previous generations / who is related and how, etc. The link for the site I used is below, free of charge but sign up is required.
Cara Legacy found her future husband at the Willow Creek library and then later had two children, Peyton and Ayden. Originally I had only planned to have the one child since my legacy said that I only needed one, however – quite sadly- she had twins which made things more complicated.
Recently I have been looking at a few challenges and decided to start the Legacy Challenge.
The legacy is basically just a 10-generation challenge which includes following certain rules and laws for each different generation.
