I find myself most attracted to normal villagers (Four of my dreamies are normal - Melba, Lily, Maple, and Lolly). I don't mind reading the same dialogue over and over again since they're always so sweet and pleasant.
My favorites (Fauna, Lolly, etc.) all tend to be normal- so I guess that solves that ! I like some peppies too but the Normals just have such sweet personalities (ha)
