This is all exactly true. But it also hinges on a second point. Nintendo develops games based around a theme. Be it thinking of a pure gameplay aspect and building from there (Super Mario Bros), setting (Zelda: Wind Waker), characters (Fire Emblem), etc.
But because they're a good company, as they have one idea to build a game, they also know how to utilize the OTHER good aspects of a game and make it work. And somehow, they can start each game over from scratch and make a whole new game work out. At least, 99% of the time. Depending of which Nintendo games you think aren't AAA quality games.
