I actually have a rather funny story to tell...
Back when I was seven or so, I saw an advertise for the new Harvest Moon Game.
I didn't know much about it, only that it had to do with animals and that I found it very cute. So I took all the money I could afford, asked my parents to bring me to the next toy store & came back with a Gamecube-game named "Animal Crossing". I wasn't able to understand English back then, I only saw the boxart with all the animals and the meadow on it... and thought I got the right game.
I played this AC for ages, really. I haven't even noticed that it was not Harvest Moon and had nothing to do with farming at all. When I found out about my huge mistake, it was kinda weird, but I was ok with it. My mistake brought me my favourite game of all times.
By the way: I got my first "real" Harvest Moon a couple of days ago, finally. It is a good game, though it can't catch up with AC, of course.
