Even if I were to allow the statement "3 powerhouse franchises" go by, then name one other party, first/third or anything, that beats that combined power. It'd be hard enough to find one that matches
that. The so-called "fluff" is enjoyed by many MANY people, from new (children) to old (nostalgia purposes). I know I love that extra option of a new Kirby, Mario Kart, Pokemon, Mario Party, F-zero, Wario, Advance Wars, Star Fox... I don't buy everything, but that extra option is great. Especially since most of these games get 8-9 out of 10 ratings. I'l get on originality later.
