Garrett is right though. Taking one aspect of a game and adding it to another shouldn't mean it's copying or ruining an experience.
Harvest Moon offers a lot more than Animal Crossing when it comes to hard manual labor. Like owning a farm, tending crops, animals, mining, buying and trading, and eventually raising a family.
Animal Crossing is, or was, about moving to a town, getting a quick jump job to boost your chances of paying your mortgage, and then furthering your house.
Anything added to Animal Crossing to make it more enjoyable, I'm for it. I would even soften up and say I'd accept cooking if they could implement it to where it feels like AC.
