To create a neighborhood, you'll need to make houses where nobody lives ( house with a question mark at the builder's) and place a lot of them around a place. Then, it will take at least one time change for people to move in. People will start walking around and staying in their houses. Sometimes they have problems, or great things to share with you. So you click the emotion that you think describes what they have to share, and if your right, they can give you blueprints or furniture items! Sometimes they'll just share something with you but you don't need to do the emotion thing. Be sure to place trees and other items around so the people will want to actually walk around! They'll be in different places and have different things to say every time change. So you can visit them whenever you want! (You can place neighborhoods in any area and however many areas you want, just not the zoo!)
