You play on in the single family for 10 generations.The 'founder' has to build their house and wealth, and then procreate to make a second generation.Create a Sim of your choice, and move them onto the biggest empty lot, but they must start in poverty (only $10,000 simoleons, excluding the cost of the lot).
Players have been doing it for years, probably since the days of The Sims 1. The Legacy Challenge is one of the oldest, most classic of Sims challenges.
