Does anyone know a challenge involving rotating from world to world?

I think the Globetrotter challenge might possibly be along those lines?

Have you ever tried the Drifter Challenge? I think it might be somewhat similar to what you're looking for. I love it, longest legacy type challenge I've ever played. I haven't played in that save since the gardening bug hit in the Eco Lifestyle pre-patch though. Here's a link to the rules:

The Drifter Challenge

My own challenge, One Month One World One Year involves living in a different world each real world month, but it's not a legacy type challenge. Sims start as a teen and stay a teen for 3 months, YA for 4 months, Adult for 4 months and are an elder for one month. You could adapt it however you like though. :) Perhaps try to do one generation per month, per world and follow the rest of the guidelines for goals? Just a thought...

Happy Simming! <3

I tried making my own, similar to this. A sim could move once in their life and only if they married someone from another place. A child stayed in place until they married someone. It worked fine for a couple of generations.

Hi @SnowBnuuy thanks for the suggestion!

I played the Not So Berry challenge that way. Also, my Years of Sim challenge:

Each generation is based on a different year of content in the sims and they have to live in neighborhoods from that year. So, the first generation has to live in basegame neighborhoods, Gen 2 can live in Windenburg or Magnolia Promenade, Gen 3 lives in San Myshuno, etc.
