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.

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

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. It is possible that Riverblossom Hills used to be Riverview, just as Pleasantview used to be Sunset Valley.
