In my opinion, Nintendo and Sega both followed similar business models of producing mainly first party software and focusing on arcade style gameplay rather than pc quality graphics. Both relied on familiar ips.
Sony revolutionized the industry by focusing more on third parties and multimedia capability, and then Microsoft jumped in after Sony.
And Nintendo realized it was better off differentiating itself by making games more arcade-like again. So the Wii is pure Nintendo. We must remember that games like "track meet" existed on the NES that utilized stepping as input, so the balance board isn't really a new idea, and wii fit isn't really a new idea. Wii fit is the new track meet, which existed on the NES.
Nintendo always targeted a different market then Sony or Microsoft. The Nintendo/Sega arcadish core gamer is different from the Sony/Microsoft pc-style core gamer. Being a very broad gamer, I play both, but Sony did change the industry majorly, but Nintendo then figured out they were better off staying as Nintendo. My point is that people who claim that Nintendo was similar to Sony and Microsoft back in the day, and then they changed, are very confused people. Nintendo was always Nintendo.
