It was released last year only to Europe. xD
I lived in USA as well, but it's not release here. =/ Again, 4kids.tv lost their rights. Hopefully, Nickelodeon will get it cause I also have a Wii and wanted to play this as well. xD
I heard some viewers say the game is fun. You can find them here about how it looks like:

You can also play in Story Mode as well along with the Winx Club. ^_^
