Riverblossom Hills

Riverblossom Hills is the pre-made neighborhood that is added to the game with the addition of The Sims 2: Seasons. Many of the lots have to do with concepts and additions from The Sims 2: Seasons. For example, many of the more expensive lots have greenhouses. Riverblossom Hills is in the more rural area of SimNation. When the neighborhood is first played, every house except for the Greenman family is in the midst of winter under heavy snow.

Interestingly, almost every 'ancestral' Sim in the neighborhood is resurrectable.

Roth Family
This family seems to be based on Pleasantview's Goth Family, as it consists of Morty Roth, his wife Stella, and their children Sandra and Xander.

Wan Household
This house consists of roommates Patricia Wan and Cleo Shikibu

Greenman Family
The family consists of Jason Greenman, his wife (PlantSim Rose Greenman) and Rose's plantbaby Daisy

Viejo Household
This household belongs to Catherine Viejo, her best friend Betty Goldstein, and roommates Andrew Martin and his son Jacob

McGreggor Family
Farmer Leod McGreggor lives almost completely alone: no family and almost no friends.

O'Mackey Family
Alexandra O'Mackey (found in the family bin) left her husband Gabe and daughter Jules to become a Dread Pirate.

Ramaswami Family
A married couple (Sanjay Ramaswami and Priya Ramaswami) doesn't know where to live

Ottomas Family
A big family of six of Peter Ottomas, Dora Ottomas, Samantha Ottomas, David Ottomas, Sharla Ottomas, and Tommy Ottomas. The mom, Samantha Ottomas, is pregnant with twins when this family is first played.

The Ramaswami and Ottomas families appear in the family bin for all neighborhoods

Riverview
In The Sims 3, a town is available for download from the official The Sims 3 website. It is called Riverview and one of the streets is named "Riverblossom Lane". It also has the country/farm effect that Riverblossom Hills had. However, no Sims from Riverblossom Hills make an appearance, but Don Lothario appears to have been teleported there from Pleasantview, and the Broke Family, the Newbie Family, and the Simovitch Family were all originally from Riverview. It is possible that Riverblossom Hills used to be Riverview, just as Pleasantview used to be Sunset Valley, and in the description of Riverblossom Hills, it says that many Sims have relocated from their hometowns and moved there, possibly explaining why there are no Sims from Riverblossom Hills living in Riverview.
