If you reset, you'll probably just get bored with the new town too. I suggest taking a break. Have you decorated your house? That always keeps me busy. I try to come up with unique ways to decorate. When I finish with one house, I start a new character house. I also like growing hybrids. It's fun to see new flowers each day. Have you caught all the fish and bugs? Do you like to make patterns for clothing or furniture? Dream towns are fun to visit. I love seeing other peoples creations.
Just redecorate your town. Move PWP to different areas, flowers, trees, etc. Change it, you don't need to reset to start something new, that is what I'm currently doing.
