Not into games

Does anyone understand the concept of the Animal Crossing: City Folk game thingy by Wii speak? I don't get it. So what is it? You call your girlfriend while you're both playing this game and you talk about all the imaginary things you're doing like "shopping" and "watching fireworks"? And this is designed for women? So like when I call my girlfriend that I haven't talked to in weeks or months I would much prefer to skip all the real stuff and talk about my pretend video game life? So confused!
