I bought the game, but my wii needs to be shipped out to Nintendo and my parents are beyond lazy.
Anyway, I heard you can buy extra songs and characters with Wii points. Is that true? How much?
It's not true.
You CAN buy characters. But not with wii points. You earn money in the game, and then you buy them in the game's store. Same with songs.
The wii doesn't have downloadable content yet.
