"NEW SECRET FEATURE ANNOUNCEMENT THIS WEEK!"

I saw a comment on YouTube from a speculating simmer that caught my interest. They said that something in the last livestream caught their eye but it was quickly closed out by a Guru. The Simmer thought it had something to do with challenges. They surmised that it was some sort of "create your own challenge" system where you choose your own checklists and goals for your Sim. I have no idea if this is on the right track or not, but the theory sounds interesting.

Edit to add: OR...it could be a "create-a-career" system. Soon we'll be able to give our Sims any job title we want, that's been verified. So this kind of feature would tie in with that. The goals checklist would be chosen by the player and we determine what activities contribute to career advancement. (And even fame.)

I think that makes more sense and could be why there aren't many new careers offered, yet fame and reputation was created to be flexible with all existing careers, and jobs and such have been a huge part of the focus of this pack.

Okay, I'm sticking with this theory.
