Having played through both SM3DW and Knack, I can officially say that where SM3DW is 10 on a scale, Knack is down at around 2.1. Actually, don't even get me started.
SM3DW isn't its own problem, Wii U is. Knack isn't its own success, PS4 is.
EDIT: I feel sorry for the incredibly great minds that worked on SM3DW. Nintendo has let them down.
Mario 3D World is part of the problem, because it failed to convince consumers en masse to invest in a Wii U in order to play it. Software sells hardware after all. When the system was struggling all through last year, there sure were a lot of people hedging bets that SM3DW would save it.
