Well my friend also gave it a fair review, but knocked it for the coins being items thing and from his point of view 'green shells have impeccable aim and red shells everywhere' while claiming some other things about the item system having a few problems, but at least the blue shell is gone.
And since this is the guy who's not buying Smash 4 since he hate the roster, despite him saying that the game play looks amazing, apparently that's a category of importance for him as well in his review, while he loves the fact you can play as the Koopalings, Rosalina, and Shy Guy, he hates the babies and Pink Metal Peach.
Also praised the graphics and music, but didn't go into tracks or anything like that.
Overall he gave it a 7.5 out of 10 because of the item system needing improvement beyond the lack of blue shell cheapness.
