your on world.....
First you have to chose a house and then you have to work for Nook.
After doing some little jobs you get the chance to do your own thing.
You can catch bugs or bees and give them to the museum or you can go fishing and get some money with selling them.
Or get your own clothes and make your own designs for walls or the floor.
And don't forget to buy something in Nooks shop,so the shop will become bigger and bigger and will have more new/special items.
Another important fact ist that you have to watch after your city and you should try to hold it clean.
A must-have for your Game Cube.
