The flight of third parties, my take on the Wii and its shovelwares

[Sky Render]

You have to understand as well that a big part of the Nintendo fanbase is ever-changing due to its demographic: children. From the very start with the NES onwards, Nintendo's primary target audience has always been children (which is a big part of why the Game Boy line was so successful; why do you suppose they always had such tightly packed controls and small screens?). The Wii and DS have branched out their target demographic considerably to not be so age-restrictive, however; about the only market they don't hold the major appeal in is the 15-to-30-year-old male demographic, which is the most overserved gaming market there is.
