I have 2, though only because I thought I lost my first copy and then bought a second, only to find the first one a couple of months later. I'm gonna use the first one as a cycling town.
Got my second copy today in the mail wanted one for ages, but I wasn't willing to spend more than ?15 including shipping and only niw I finally got one! (For under ?14 )
I want to use it for cycling and to easily earn gold weeding/streetpass/host/visitor badges in my main town. Then, after I'll be done with cycling I want to find a perfect map and turn it into Hogwart themed town
I have 2. I wish I could have more but that would probably be overkill for me since I have a toddler running around all day and have other games I play lol
I mainly got another town after I lost Mochi the first time (got it back thanks to powersaves) lol. The idea of starting a new town had me super excited, but I didn't have the heart to reset Mochi. So I got another copy and I'm super happy! It gave me a chance to do things differently and make changes I couldn't do in Mochi anymore because it's complete.
