The first probably sold due to it being a launch game.

Now a few years later they snap announce and release the game, completely change its title and format. Making the game (superficially) look like any other shovelware release and then expect it to sell? To who? The 15 million who already own Mario Kart? A franchise over a decade old and starring the most famous games character  in the world?

That was all plain to foresee though.  What more did they expect?  Why even make a game so doomed?  Maybe someone at nintendo should have shown some tough love at the early stages of production.
