I have ten active towns and I have only reset once. It was my town of Paradise and I had foolishly thought I wouldn't mind the long trek to the Retail. I was wrong. The entire map just was awful and after Sitches moved out after a time traveling bungle which was entirely my fault, I was heartbroken. So after much deliberation and INTENSE guilt, I deleted the town. The only good part of the entire experience was that Stitches showed up via the Void in my daughter's town the next day. But yeah, I take restarting towns very seriously. Being a complete psycho, I really get attached to my villagers and deleting them or sending them to the Void always causes me pain and suffering.
