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.

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