Mario 3D Land caused a nice spike for the 3DS though. From 66k to 137k (Mario 3D Land week).
I think branding the game "Mario 3D World" was a mistake too. For starters it doesn't really even make much sense as the 3D bit in the SM3DL title is to reference the 3D screen, second it just gives the impression of "well I already have this game on my 3DS, why should I buy a Wii U for it?".
