"New Super Mario Bros. 2 was a good game, but I couldn't help feeling disappointed with it. The first New Super Mario Bros. felt like a breath of fresh air, a welcome return to the past in an age where such simplicity had been forgotten. The right bit of nostalgia at the right time can feel incredibly new.
The sequel was not that. Already following New Super Mario Bros. Wii and Super Mario 3D Land, it didn't feel old-school as much as it felt plain old. Still good, but wholly unambitious.
With the advent of New Super Mario Bros. U, I now know why it lacked adventure and inspiration. Nintendo had clearly already spent itself working on this little bit of greatness.", writes Destructoid.
