I've reset my town 6 times because I wasn't content with how it looked. This was mostly because I always copied how other towns looked so it wasnt really 'my town'. Now I just make my town how I want it so I like it the way it is now and I dont plan In erasing it anytime soon.
Being able to put a couch or a fridge in your pockets. Or when buying coffee you put it into you pockets, how painful is that! I also feel sorry for Kappn, he works 24/7 :P
I have three since I have a lot of paths and you can only hold 10 patterns per villager. I hope in ac switch there will be more space for patterns and more inventory, sometimes it gets annoying due to there not being enough space :D
