All nonesense, Sony gets away with releasing the same types of games on Playstation and nobody notices. Nintendo has a weird audience and a weird culture that is all. Nothing they do can ever be rationalized no matter how hard we try it's always just mindbogglingly odd. Sometimes they get lucky and it works, sometimes they shoot themsevles in the foot but watch documentaries on how they stumbled into the NES, it was blind damn luck it took off nothing more, same as Wii, SNES they fought for and almost lost, the N64 and GC they did lose, they are not at all able to predict what will and what won't work. But to be fair, in video game at least, nobody can predict what will work and won't you could argue Sony has been lucky to some extent too, but I think they fight harder than Nintendo does.
