When you begin the game i think it is the personality you do not have, for instance my first 6 villagers were Normal,Peppy,Snooty,Lazy,Cranky,Jock. Therefore when resetting my game for the seventh, the only villagers that came up were Uchi and Smug, and i got Cherry an Uchi. So tomorrow i know for my eighth, it will be resetting for a smug villager (ill try and get Marshal or Henry)
That sounds right but in my town I started with Peaches, who is normal. My seventh villager was Bluebear who is also normal. Now, the only possible clause here is that Bluebear moved from a wifi friend's town.
Another thing, I don't know what this means but I feel I should mention it. I am due for a ninth villager, I got Zell the first reset and then O'hare the second reset, then after that no new villagers at all. Both those villagers are smug.
So I don't know either way what the game does when a new villager is moving in.
