ACWW is the original plus some extra stuff topped the wonder of Wi-Fi, all in a DS package that is loads of fun!

User Rating: 9.7 | Animal Crossing: Wild World DS
Animal Crossing: Wild World works the same way as Animal Crossing for the GameCube: You move into a town where time flows in real time and where animals live and you pay off your house to get it bigger and better. All the other basic stuff are still there (Fishing, bug catching, the museum, Tom Nook, Fossils, K.K., seasons etc.) that made the original all the fun it was. I does add some other features like listening to the animal's conversations, much more personal personalization options that include hair style and colour, glasses, hats, and more, the ability to create constellations to be viewed in the night sky on the top DS screen (unless you are doing things like typing or other stuff -- or you're inside). Probably the most important new feature is the most obvious one: you can play anywhere!
Now ACWW surpasses AC by a lot in multiplayer play... well unless you're using the same game cartridge. Unlike the original, all four players in a cartridge are in the same house (I have yet to try out how this works out but it seems like it could get a bit interesting at times!). Then there's the wonder of Wi-Fi. Easy to set up and it's tons of fun to play with other people. To play with others with Wi-Fi, you need their friend code, the only setback but a good security precaution, unless you find a fan site where you can exchange them! One thing to note is that Wi-Fi is far from being flawless. I have more than once met the BSOR (Blue Screen of Resetti where a blue screen with our old friend Mr. Resetti (yes, he is also back in the game it self) comes up telling you the problem and even noting that the game will reset and you'll lose data) so ask the owner of the town you are in to save from time to time.
Animal Crossing: Wild World takes almost everything from the original, stuffs it in a DS, sprinkles on some extra stuff then puts a Wi-Fi cherry to make it a time-wasting experience not to be missed!
