I agree that the fair majority of the kinect stuff was really unimpressive. That Star Wars game looks heinously bad, what with you literally flying/floating to each new enemy. I wish they would realize that they can use kinect in cool ways but it doesn't have to completely dictate gameplay. ME3 was a good example where you ostensibly still use a controller for pretty much everything but you can issue squad commands and choose dialogue options by voice command.
If this article's idea was used on any child older than 10 it would only result in some pissed off kids. If someone is immersed in an activity and you suddenly rip them out of it ... well, that's a dick move. Whoever wrote that article clearly doesn't have any concept of how to interact with today's youth. Want your kid to have a good time with you? Take 'em out to your nearest surviving arcade and waste some dude in Time Crisis, but only if the machine still has the guns with the chambers that kick.
