Its a FACT that Mario is an easier game to play than Final Fantasy. There should be no argument there. I can assure you that the "13" after the final fantasy name will confuse most non-gamers. CGI appeals to people. But I can also assure you that a non-gamer will be able to pick up and learn Mario in about 10 minutes. I'm not even sure that you can do the same with Final Fantasy.
Are you going to argue this point with me now? That FF is easier to play than Mario?
And like I said before, when you've sold 6 million copies of a game in 3 months or whatever, OF COURSE THE TREND IS GOING TO GO DOWN. I'm not going to expect that SMG will sell at this rate forever. Even if 0 copies of SMG are sold from now to like forever, SMG will be considered a HUGE SUCCESS.
