Your favorite Challenges!

I've only done one and I'm still in the early stages of it, but it's the Build a City Challenge.
I also think the Royal Legacy, Royal Kingdom, and the Castle of Cards challenge sound interesting. I haven't tried them yet though.
And then, I was inspired by the Classic Movies legacy challenge to make up my own movie challenge based on the films of one of my favorite filmmakers; maybe you could try doing something like that.

I like the drifter challenge. Each generation has their own unique goals and career challenge. Plus you start with empty willow creek and oasis springs and add houses/ new building type each generation so you also end up with a customised world for your sims.

Cool! Can I have the links to these?

The everything challenge is cool. You have to master all skills, aspirations, complete all collections, live in every world, use all traits and so on... all of this during several generations and with different sims.

Legacy Challenge, Flargen Challenge, Big Brother Challenge, Murkland Challenge, Not-So-Berry Challenge, etc.

DITFT is a good challenge - https://forums.thesims.com/en_US/discussion/comment/16878809

Yeah I just started the zodiac challenge and I’m pumped for it. It’s over on reddit in case anyone is interested.

I'm currently trying a rags to super sim challenge, starting my sim with no money and no house and trying to do everything in the game - has just got enough money together now to have a roof over her head!
