The original Legacy Challenge was created by Pinstar in 2004. He originally created it for Sims 2, and later updated it for Sims 3 and Sims 4. He has an entire website dedicated to the incredibly detailed rules, as well as other challenges that he has created.

The Career Legacy Challenge is currently being played and developed by Risshella on her Twitch stream. She is playing through every career in alphabetical order and she has also added in extra goals for Hard-mode and Optional Side Quests.

This is another classic challenge that has been around since the Sims 2. This Sims 4 adaptation has various difficulty levels, as well as a regular scoring system vs. an advanced scoring system, depending on what level of chaos you want in your game. This also adds quite a bit of replay value, because you can start on "Novice" and work your way up to "Legendary". There is also an in-game achievement for outliving 5 spouses called "Black Widow", but this challenge goes all the way to 10 spouses!

This challenge has been around since the Sims 2, and I still love the concept! There are 3 different difficulty levels that you can try, depending on the level of chaos you're interested in. I also love the idea of building the run-down asylum. Although, if you aren't a builder then you can always check the gallery for an asylum under #AsylumChallenge.
