What exactly is it that draws Animal Crossing players, it's not only one particular thing. For closet hoarders, we could buy and collect every possible piece of furniture which makes a full set- something very difficult to do in person (and more expensive), while other people can simply relax using a day of fishing, bug hunting, fossil collecting, to see them on display into their local museum, reading different info on them.
You can use the things you find to exchange for money to in the house. This is a step-by-step system that works perfectly. If you want to make a lot of money, it is also possible. If you want to relax and talk to your neighbors, you can do it too.
It's that simple. Animal Crossing can be addictive because you are free. Express your wishes, decorate the look we want with this virtual world, express satisfaction or friendliness to your good neighbors, and they will continue to get along with you no matter how you treat them.
