Nintendo's meteoric rise on the stock market brings with it new challenges.
The phenomenal success of Nintendo over the last three years is hardly a new topic, either for this column or for the industry in general. You know the drill by now; by innovating with proven technology and delivering low-cost products with new user interfaces, the firm has propelled itself back to the top of the market, and is handing Sony and Microsoft their backsides on a week to week basis in every major territory on the planet.
Despite occasional lapses where people who should know better argue that the Wii is a "fad" (if that's true, what does it make the Xbox 360 or the PS3?) or that it isn't a "proper" games console, Nintendo's success is largely accepted as a major feature of the new territory games firms must learn to navigate.
What hasn't been discussed in the same level of depth, however, is that Nintendo's sudden market dominance with the DS and Wii is strengthening more than just the firm's installed base.
