The game is one of the best for the DS, and also one of the funnest.
Its about a citizen you make living in a city you name.
These are some of the many things you can do in AC:WW-
+Buy furniture,clothes,plants, shovels, etc.
+Collect things like fossils, fish bugs, etc.
+Spend money on house upgrades, store upgrades.
+Talk with animals, do errands, etc.
+Got visit your friends towns using wifi and FC's(Friend Codes)
So basically there is lots of things to do, as well as lots of cheats to make the game funner *cough* cheats *cough*. So if you have $30 and want a new DS game, then buy it. Trust me, you wont be dissapointed
