Building your own home gives you creative freedom to create the perfect, personalized home for your Sim. However, if you want a challenge—and would like to start with some larger homes that are fully furnished,complete with Sims—then try playing one of the pre-made households. The Sims come already created and have personalities and situations that can make things interesting. To play as a pre-made household, you first have to create your own Sim. Then once you start a game, go to the main menu and select Manage World. This opens up a view of the world you’re in and allows you to travel to the other world. Click on one of the homes with a Gray Plumbob over the top and then choose to play as that household.
Some of the households are more difficult to play than others. As a general rule, the more Sims in the household, the more difficult the household is to play. However, the dynamics of the Sims within a household can also provide unique challenges. Be sure to try playing as each of the pre-made households. Not only are they fun, they also provide some experience that will help you when playing with your own Sims—and give you a head start on money, a nice house, and skills and careers.
