Sunset Valley

Sunset Valley is the only neighborhood being shipped with The Sims 3. It is very large compared to the neighborhoods in previous The Sims games, having a total of 97 lots with various playable characters. There are lots of different types of houses like, a rustic home on a hill, a modern house in the suburbs, a house by the beach and many more. The main part of the town is the park, where you can have a picnic, go fishing or take a stroll and maybe meet someone new, there are also cinemas, gyms, restaurants, shops, pools, and other recreational facilities. Tons of places to work, where Sims can live out their dreams or crash and burn. Sims can now visit all their friend's and neighbor's homes. Call up there friends with the new cell phones, and go out on the town and party.

Sunset Valley is Pleasantview before the original in The Sims, which the neighborhood is named Old Town. The Goth Family will be there as their younger selves, presumably, Mortimer as a child with his parents, as well as many other familiar families, including the Bachelor Family and possibly the Pleasant Family. So far all known new families include the Altos, Wolffs, Hart, Ursine and the Keatons. The Landgraab Family will also make appearances.

Mrs. Crumplebottom will be around as her younger self. The source of her crabbiness is revealed to be due to her husbands death, her husband features as a ghost.

The Hart Family appears to be a normal family...well except the fact that both the mother and father have the insane trait. Their, daughter Bebe is just trying to be a normal teenager in this chaotic family.

The Ursine Family or Claire Ursine is a single lady who lives alone and loves to fish. Though her life may seem uncomplicated, she is currently pregnant and has a job in the criminal track.

The Altos Family is simply described as "Nouveau Riche and Evil." Their family name may be a pun on the television series "The Sopranos."
