Paper Mario was totally unique, but also I doubt it was pitched as the successor to the higher rated game of all time. You must look at the context when understanding peoples dissapointment. Alongside the above, this is Nintendo's flaship title of 2013. Is it really hard to see why people feel a bit cheated
I understand his dissappointment and as I've explained countless times I don't believe this will be the definite 3D Mario, successor to Galaxy. It's a nice title made by the 3D Mario team prior to Galaxy to get the U going, much like 3DLand.
Also, I was just addressing his argument standalone as I've argued his dissappoinment in its context over and over, so I felt the need to address the flaw in that post but that was assuming 3DW is not the Mario he was waiting for and that there is one in the pipeline (obviously).
