The Ultimate Sim Challenge was created by @Llandros2012
and is basically a challenge where you do everything a single sim can do. You have to do every skill and skill challenge, and also complete every college degree. There are too many rules to list here so I am including his originally rules below. I'll put the first two updates up today and will add to them over time. I started the challenge on December 11, 2018 so most posts will be a couple months old.
