Super Mario 3D World is such an unbelievable upgrade and sequel to 3D Land. Whilst 3D Land is still good and hasn't gotten worse since this released, 3D World is just so much more beautiful in its levels and music, to where almost every track is memorable and the gimmicks are fun and don't overstay their welcome. The co-ops makes this game a lot more replayable, as I've played with a few groups of people and it's been different every time. I'd have mastered 3D World by now if it weren't for having to do Champion's Road 5 times in order to 100% it properly.
