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

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.
