The Sims 4 Decade Challenges Guide

The Decades challenge is where you raise a generation of Sims from the 1890s onwards in The Sims 4, limiting your lifestyle to each era.

Are you looking for some fun challenges to spice up your Sim’s boring lives? Then the Decades Challenge might just be the right one for you!

The Decades Challenge in the Sims 4 was created by ZombieCleo. This challenge includes a generation of Sims starting from the 1890s that advances through decades, accepting and bringing about the changes each decade presents.

The Decades Challenge gives you a first-hand experience of how society advanced in different eras. This challenge takes you on a time travel and lets you experience gender norms, wars, revolutions, occupational restrictions, ethnic restrictions, and much more.

The Decades Challenge in Sims 4 has a very extensive set of rules, each detailed with much complexity. Some of these rules regarding war, same-gender relationships, gender norms, etc. can be sensitive and you can skip through them. But, if you are looking to have a complete experience of the historical timeline we suggest that you play by the rules and travel back from the 1890s to the 2020s!  

The Sims 4 Decades challenge rules

Each decade in the Decades Challenge has its own set of rules. Your Sim must wear era-appropriate clothing, use the technology of only that era and have residence and status accordingly. This will give you the actual essence of living through the decades.

There is no need to get the custom game pack for this challenge but you can choose to do so to enhance your experience.

Following are some rules that you should abide by while starting the Decades Challenge in Sims 4:

  • Starting Sim: Your starting Sim must be a Young Adult or a couple but both of them must be Young Adults.
