There can always be arguments made about who makes the most revenue vs profit vs market share but the thing that Nintendo has that no one else can compete with is the strength of its intellectual properties. No company on earth can compare to that other than Disney... and even it can only compete due to the acquisitions it's made over the years, like Star Wars and Marvel. Mario has been more recognizable than Mickey Mouse for over 30 years now. Even among Americans.
Third party support is always important, but Nintendo is in a far better position to stand the test of time than Playstation, Valve, or anyone else in the games industry. Why? Because even when it slips up here and there with its hardware, Nintendo has maintained such a high level of quality regarding its key franchises and making its games enjoyable. So far, anyway.
