The Wii, devolving the human standards for typing. Why use an On Screen Keyboard when you can use an actual keyboard and type 15x faster?
@Seppuku, I can not imagine a game which would teach the child to plung their wii controller into their stumac. Well, maybe a japanesse cultural lesson 'game'.
Personally, I can't see a Wii game being that innovative, and from the reviews I have read (not all being 'wii sucks') it seems to come down the the sad fact that your skills in tennis, for instance, will not translate over to the wii. That in the end, you are just pushing a different button, one that is three dimentional in nature. Simply flicking the remote between your fingers probally would produce the same result.
At most, I would say the Wii would bring about a sense of false ability... meaning that these Wii players might actually believe they are expert swordsmen. Go out, and get themselves killed... There is a lot more to sword fighting than you can learn from swinging a wii controler, or brooms, for that matter. For one, the general balance is a lot different than what all these movies portray. And if someone doesn't hurt him/her while she/he is trying to finally grasp that... she/he will get hurt while attempting to swing it (not realizing the momentum).
If you fear speaking for yourself, make use the words of others while discovering your own voice.
