Ken McKown writes: Being a launch game on any platform is not an easy task. Knack looked to be one of the shining spots for Sony’s PS4 launch. Unlike most of the lineup, it showcased a more lighthearted look and feel akin to Nintendo launching a new Mario with their platform. It also helps that Mark Cerny, the current face of the PS4, was behind its creation. After plodding through the 10-12 hour campaign I can safely say that Knack crumbles under archaic design and tedious progression. There is just not enough charm here to make it worth putting up with.
