there is a hole in your argument, guitar hero world tour, and rock band too include more intruments, and they were tested by pro in the music business travis from blink 182, they were made to simulate real drums, not being them, but waggle to make a sound it not closer than guitar hero or rock band are.

and also both game have some archivement into it, hell a score , wii music doens't have that, you pick a instrument and waggle that its.

how amazing its that? nothing impressive at all.

They were made to simulate the instruments, not the music. There's a difference. Unless hitting on the drums makes extra sounds (not sure), the music is seperate.

Do you play instruments? When I used to play violin, I don't recall being scored when I was satisfied with a song. It didn't require anyone "scoring" me to get satisfaction out of it, just myself recognizing it sounded good.

That's not entirely true from what I have seen ...

The Wiimote motions may not be designed in such a way that they can fully replicate the sounds produced by an instrument, they do appear to be able to reliably produce the same impact on the sound produced. Now, you may have a problem with this but I don't see how this is any different from playing a toy-guitar that only has 4 buttons and claiming that it replicates playing the real insturment.
