About Mario:
To get NSMB Wii you had to spend 200$ at the time of release (assuming you had to buy the console, in 2009 a lot of people already owned a Wii), to get NSMB U the price was 400$ (or 350$ if you really wanted the basic bundle), and you had to buy the console anyway since it was a launch game.
About portable Mario, NSMB DS was the 1st 2D Mario game released after 15 years the install base was larger, the console was chaaper by 50$.
Add that the state of the economy in 2012 was worse compared to 2006 or 2009.
Add the fact NSMB2 and NSMBU were released at the same time.
P.S. New Super Mario Bros IS NOT a casual game, neither is Mario Kart.
