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, such as many of the more expensive lots have greenhouses. Riverblossom Hills is placed in the more rural area of SimNation.

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

Riverview
In The Sims 3 a town is available for download from the official Sims 3 website. It is called Riverview and some of the streets are 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.
