It is inevitable really. The Wii gesture controller can involve far more athleticism in gameplay than the joypads of non gesture interface gaming platforms. Add to that the addictive quality of games that sometimes has people playing for longer than they ought. Then the competitive nature of gaming. Then older and less fit players not wanting to be shown up by younger generations. And you have a recipe for problems.
Of course people will learn as this becomes more of a part of popular culture. But in the meantime it is giving the popular press a field day for articles and has even led to the creation of websites cataloguing people’s Wii stupidity. Imagine what is going to happen when there are a few million balance boards out there.
All this is good for the gaming industry. It has the real world talking about us. And the only negativity is people’s own stupidity. Which is a universal factor of life anyway.
