Just a reminder that Nintendo and others have been innovating well before the Wii
This bit particularly hit home when thinking about the Wii in comparison to these old controllers:
In fact, much like R.O.B. or the Roll & Rocker, all they did was make games harder to play. Mario's not hard to get the hang of the regular way, but when you were waving your hands around in the air, hoping in vain that whatever cheapo assortment of plastic motion sensors that you got for Christmas would pick up your body movements, the result you usually got was something short of total mind-candy immersion. It was closer to "endless game overs."
