I saw a ‘Riverview’ neighborhood mentioned in several articles, but when I went into the New Game option of Sims 3 and looked at the neighborhoods, it only had Sunset Valley. I searched for it online and some articles said it was available when you registered for the game. But I don’t remember seeing it. So if you never got it either, you can download it for free from The Sims 3 Store like I did. But wait! you can’t search for Riverview in the store search feature! If you go to the Sims Help and search for Riverview there, you’ll read the information about it and find the download link. Here’s the link to the download page (you must register your game before downloading): Download Riverview
