I've had a lot of towns over the years. I started playing Animal Crossing maybe Christmas 2002 or 2003.
Gamecube/Population Growing - I had two memory cards, one came with the game and the other we bought separately. On the main memory card was a town called Mew (based on the sound cats make); it was my very first town and my favorite villagers lived right next to each other: Bob and Mitzi! My second town, Pokey (based off of the red horse in Gumby), had a ton of apples, and that's about all I remember of it.
Wild World - I had one copy of AC:WW, and I named the town Mew. There seems to be a trend with my town names, that's for sure!
City Folk - One copy, one town. I restarted twice, and both towns were called Mew.
New Leaf - I had two copies at one point. My cartridge had a town named Mew (Mayor Aly). It was a very well developed town; I worked on it from 2013-2016 and had all of my dreamies. The town fruit I recall was the cherry. I had Carmen, Felicity, Rosie, Ankha, Punchy, O'Hare, Maple, Fauna, Stinky and one other that I can't remember. My digital download copy held the town of Pokey (mayor Marie), another perfect town with beautiful PWPs and flowers everywhere, with more of my dreamies, including Tom, Blaire, Purrl, Mitzi, Freckles and Bob.
Now, I have the town of Eureka (mayor Junie), and thanks to Amiibo I have Carmen (waiting on my Punchy Amiibo card); my town fruit is once again cherries! I do not plan to get a second copy of ACNL again so I will just be sticking with developing and growing Eureka!
