I'll go through Manage Households and delete the townies that don't appeal to me and edit the ones that do. I came across an Asian-named female Sim and thought she had potential, so I went into fulledit mode and gave her eyes just a little more of an angle and changed her hair style and color -- turned out she was a vampire as well so that's very cool; I may actually save her to my Library and put her in my main vampire save for my klepto vampire to meet and romance.
