They were, when they were introduced. But because most of them is what we grew up with, we consider as normal and it becomes abnormal if it isn't there anymore. Give it 10 to 15 years and these things will be normal as well.
Most of those stuff was first incorporated in the gamepad by Nintendo. Nintendo became big by introducing new things. Because they settled with introducing new stuff with the gamecube, it was that many of its consumers went to other producers like Sony and Microsoft. Sorry, but if a company was failing as much as Nintendo did back with the Gamecube, it is only understandable they would target a new group.
And microphones, motion sensors and touchscreen interfaces have been around for a longer time in games, than that Nintendo added them to the DS and Wii. Hell Nintendo was already making products like that for the NES.
All I am saying is, that if you don't like it don't buy and don't play the games. Just bitching about this is growing tiresome. Don't like it, don't keep coming back to it. Nintendo is a company, it is not something that deserves our unwavering loyalty to buy their products. Because that is what all this whining sounds like. Like a fanboy child that is not allowed to go across the street from his mom..
