Old Animal Crossing fans will become familar with the interface, but not even those will care about moving into it.
You are basically someone coming to this little town, which you can name. From the looks, it was probably once populated, but hardly anybody is there when you go. The mayor is giving you some stuff to do, like find her grandson. Turns out he is at the Tennis Court trying to attract tourists and other people to the town with what he calls his 'funny' costume. Basically, all you do in the game is talk to people and make them feel better. Sometimes, you are doing errands, but they aren't much. Most all the time, they are too obious. You're not going to do anything new. It keeps the story short and lacking.
The interface doesn't have much to say, exept it looks like Animal Crossing on the DS. Same text, same looks, same stuff.
There is sort of a money system in the game. You get money from minigames such as tennis, or talking to tourists and making them feel better. You can spend it by using the trolley, throwing some in the fountain, or just spend it on furniture and stuff for your room. Your room doesn't have much to say exept it has nothing special about it. So what you can put a radio in your room? Try to turn it on. I dare you.
MySims on the Wii has a lot more to offer than on the DS for just $20 more. By that, I mean buying the game for the Wii is a lot more worth it and you'd get a lot more. When you first play it it does appeal, but when you do find your Animal Crossing: Wild World game, chances are you'll play that more.
