TS4 Royalty & Legacy Expansion Pack

About 10 years ago, I helped develop a dynasty challenge on Carl's Sims 4 Guide and Forum. It was called the Rival Dynasties Challenge, and we had fun with it. It was intended for rotational players, and the idea was to start 3 families in a 15-lot neighborhood, and see which family was the first to acquire 6 lots by moving heirs onto the property. I haven't played with that challenge in a long time, but it has occurred to me that now might be a good time to dust it off.

Here's a link to the Challenge, if anyone else is interested:
