The Adoption Challenge is a player-made challenge for the Sims 4 that tasks you to start with a founding family and work your way to having ten generations of the same family line, with the catch that you have to adopt all the children. Additionally, every generation that passes you have to adopt more children, so your founders will adopt two children and much like a Legacy one of them will become the Heir of the second generation. They will have to adopt three children and so on until you hit ten generations. By the time you get to the tenth generation you will be struggling with space and no doubt all sorts of other issues. So lets see how it goes!
