3DS has 3d parental control. Anyone with a young kid and a 3ds would know that. Well almost anyone.
And when is the last time you guys picked up a Wii controller?
Go dust it off. You'll see an analog stick, dpad, 4 main buttons and 4 lesser buttons along with a home button. That's in addition to......drum roll please........... motion control.
Also what was the last Wii game you guys played? WiiSports? Almost none of Nintendo's games use just motion control. The control in most is actually pretty darn traditional. Motion Control in most Wii games is more like Rumble is to games. It's used where it makes sense in the developer's eyes to enhance the experience.
The main method of control in most of Nintendo's Wii games are buttons, dpad and analog stick.
