One the only things that kept Rhythm Heaven Fever from getting a perfect score was the game's lack of language options. Unlike the cartridge-based Rhythm Heaven on the DS, there were no space constraints on the Wii limiting Nintendo's capacity to give players every version of the game's soundtrack. The fact that U.S. Wii owners were only given the English rendition of the Rhythm Heaven Fever experience something to frown about.
I wouldn't blame the Europeans for gloating about this. You've been waiting a lot longer for this game, so it seems only right that that your wait will be justified with more content. When Rhythm Heaven Fever comes to Europe as Beat the Beat: Rhythm Paradise on July 6th 2012, it will allow you to play in either Japanese or English. No word yet if the Japanese only "Manzai Birds" game will be available in the game as well. If it is, then Beat the Beat will officially be the only version of Rhythm Heaven Wii that anyone could ever need.
