Nintendo has diverged from the habits of Microsoft and Sony in many instances. They seem to be assimilating at least a little bit, however, on the topic of having consumers pay for downloadable content.
In Japan, where Nintendo has released a Fire Emblem game for the 3DS, it will for the first time ever allow customers to exchange DLC for money. The additional content for Fire Emblem will reportedly cost a few hundred yen, with one dollar worth around 77 yen as of this writing.
Japanese newspaper Nikkei expects paid DLC to be available for Wii U in the future.
