Its not a matter of being a Nintendo fan, its a developer perspective of how it can be used. You seem to like to ignore my points but yet further complain about the device. Are you just here to complain then, even when I've given you a logical application for said device?

That's not a good answer... This a forum for discussion.  I want to know why someone at Nintendo thinks this would sell.  I am pushing to know exactly WHY I should want to buy it. 

I don't want a rationalization or a "It would be cool if", why would it be cool if... the VS was used in an Eternal Darkness type game?  What makes you think that my heart rate while playing a game is significantly effected in a way that couldn't already be predicted by common reactions or my skill.... if the VS was used to see how many enemies to put on screen? Why is this better than measuring my skill?  Why is it better to continually up the challenge (without consent) when a lot of enjoyment comes from getting better at a game and mastering what others cannot or what the developer thought would be a good challenge?

These aren't attacks, these a genuine questions... Why is this going to make gaming better?  Neither Nintendo or anyone in here has explained to me what makes this something I should spend $20 (a guess)?

It is perfectly reasonable to be opposed to a company releasing a product for various reasons.  I love Nintendo.  I am willing to bet that a lot of people who bought Wii Music came away from that experience feeling like they did not got their money's worth and would trust the Nintendo brand as I, and many of you, have come to trust them (These are casual/new gamers and they don't read reviews - which don't really align with casual interest anyway.)

Releasing stuff like this is bad for business in the long run.

Marginal sequels and cheap novelty (as opposed to intriguing and exciting novelty, i.e. innovation) are going to kill off the interest the general public has found in Nintendo.

The reason why Nintendo succeed was because they did things no one ever saw before.  That is ultimately why Wii Music hasn't had the staying power like Wii Fit, Wii Sports, and many other casual titles. 

Almost everyone has seen a heart rate monitor.

I see what you are saying but I don't think games should tell me how I feel, they should try to influence the way I feel.
