I was responding to AutumnWind's comment about the two of them being rated just as highly.
SMG's cult following wasn't shown so much on the Wiichat boards as other review sites and such. Far more 9.5/10s and 10/10s than one would expect. The "Mario bump" I suppose, but the word from the trenches seems to paint a different picture.
I still want to get it though and see for myself.
