My GF bought a 3DS just so she could play AC: New Leaf (she has a WiiU, but couldn't wait for AC to come out on it). She loves that game and spends 1-2 hours a day on it. 17 million bells at last count.
She also spent years playing the old version on her Wii, and also has KK Slider and Tom Nook stuffed animals.
If I spent as much time playing TM as she does AC, I'd probably be a lot better at it.
