The Drifter Challenge is a 24 part challenge created by Vihisha and can be found here.
I decided to begin this challenge after I read about it in The Sims 4 Forums. The challenge seemed to be wildly loved by many fans and it looked quite fun. I plan on completing more town filling challenges after I complete the Drifter Challenge because I enjoy creating towns from nothing.
