I now truly believe that the ad wizards "don't get it".Grey Carter said:"Even people who played games when it used to be just one big red button and a D-pad can't play games now," she said. "You have to master face buttons, triggers and they all do different things, so obviously we're never going to get to that really mass-market place where we're touching a really broad audience with our messages with controllers, so Kinect and other more natural ways to interact with games are incredibly important. I think we can go further."
They assume that people won't adapt to a control scheme to a hobby they enjoy, when it's incredibly hard to find a human being without the rudimentary skill needed to work the average keyboard - arguably the most intense choice of inputs possible. They assume that someone can't get more accustomed to it over repeated use... and that most people don't have the patience to bother (which might actually be true).
Then you look at motion controls and see how people fail with that as well (initially). Some are hard pressed to find a good fluid muscle movement needed to repeatedly hit strikes in Wii bowling - now imagine someone who will never get the perfect pitch momentum in a baseball game for kinect (or perhaps, even in a real holodeck). They assume (again) that natural-feeling controls like that are easier to master, but it only states a case that using a controller with face-buttons and triggers will take far less time and personal-commitment to master. Not to mention effort, and how much energy does the common man have to expend on his gaming hobbies these days anyway? It cuts down on playtimes in tune with how much possible strain there is on the body.
Long story made short, motion control ideology is ass-backwards.
