some sales numbers over on Gamasutra, but was asked by Nintendo to take the numbers for its platforms down. According to Hill-Whittall, Nintendo doesn't allow developers to share digital sales numbers for self-published WiiWare and downloadable DS titles.
That's an interesting tack to take, and Hill-Whittall argues that it hurts smaller developers who might need to make those sales numbers known in order to secure financing or plan out their business. He doesn't see it as surprising, however, because Nintendo doesn't allow developers to change their prices or offer demos or promotions either, which are all tactics that Microsoft, Sony, and other digital publishers have used to pick up lots of digital sales before.
Obviously, not everyone will want to share sales data, and Nintendo itself must see this data as valuable information to be protected. A restriction on sharing the data, says Hill-Whittall, could be fatal for a smaller developer like his, especially if they rely on Nintendo's platform alone.
