Animal Crossing: Wild World features a very minimal plot. The objective of the game is to pay off a debt to Tom Nook, who allows the player to move into a house he owns. If the mortgage is paid off, the player's house will expand until upstairs, left, right, center and back rooms are included. This is slightly different from the Nintendo Gamecube version, in which the finished house only consisted of a basement, a main room and an attic. While paying off the debt, players can do a variety of optional tasks, including interacting with other villagers and filling the catalog of the things they have, like furniture, fish, clothes and stationary.
Animal Crossing: Wild World makes use of several of the Nintendo DS' features, including the touch screen, dual screens and internal clock. The touch screen is used for menu navigation and interacting with the surrounding area, including movement, using tools, talking to other villagers, entering buildings, picking up items, etc. The dual screens are used to display the overworld on the touch screen and the sky on the top screen, which varies depending on the circumstances.
HINTS
MONEY
Furniture
When it is time for the flea market, walk by, or talk to everyone who is outside. Then go inside your house and choose a lot of furniture that you do not want. This will also work with flowers. When someone comes to your house, greet them and they will walk around. When they stop to look at an item, talk to them and say that you will sell it for a low amount of bells. They will say that they think it is a low price. Afterwards, walk out of your house and they will also leave. Go back inside and another person will appear, saying "Low prices? I'm in." Do the same with everyone, and you should have enough money to go to other houses and get whatever you want.
Working
If you have one character, create another one and talk to Tom Nook. If you cannot find him, go in your house, then come out. He will talk to you and ask that you do a part time job. Finish all of the tasks he gives you. When you are done, he will give you 12,000 Bells. Drop them on the ground in front of your house. Before you kick them out of your town, get your other person and collect the Bells from the front of your house. Then, kick them out. The mortgage does not go up with them, but it does not go with the more people that you make, either.
