I remember I called my first town Taratown. It was my first Wild World town and the reason I called it Taratown was because I had a friend called Tara who named her town Taratown. We thought that if I named my town the same as hers we would be in the same town (like if we lived in a wifi town). We were only 5 at the time, and at age 5 it was some mad logic.
I can't remember exactly - it might have been the name of something from Final Fantasy Revenant Wings (the DS one) - but I do remember my Wii town being called Twinleaf because that's the starting town from Pokemon Diamond/Pearl/Platinum!
I wanted to be different and not name it Hyrule so instead I named my ACWW town Zelda xD I reset a lot with that game though and changed town names and themes a lot
