Nintendo concerned with bad Wiimote use, issue instructions
The above message comes direct from Nintendo, following the many reported injuries and catastrophes that have been the result of long gameplay sessions. It's OK, we understand how it goes; playing Wii Sports can be vigorous and we've been guilty, on many an occasion, of perhaps getting a little too into it. And where we'd normally snicker at emails such as these, this one, we feel, is warranted.
