I'm more of a Smug/Snooty guy as well as Lazy. Haha
I've been plot resetting for days now and every day she would appear placing a plot. Is there a set number of villagers that would move in? (I mean, every time I resetted I got Tabby, Rosie, Gruff...almost all the time.)
If you have eight villagers, the next move in will be a personality that you do not have or are due for. So if I have all personalities except for a lazy, a lazy must move in. If I don't have a peppy or lazy, but my 9th villager that recently moved out with a lazy, I will be due for a peppy villager.
I personally do not like peppy or snooty villagers. I really did enjoy having Rosie in my town though. She was adorable and a lot better than some of the others out there. I feel the same way with Diana. She is the one I'm most content with out of the snooty ones, and Rosie is my best choice for peppy.
