Noby Noby Boy is an important step forward for videogames as a whole. It puts a dollar value on an experience more akin to a box of LEGO than a true gaming experience. It's a decidedly risky move – providing a plaything that has ultimately very little payoff for players (wiggle 'BOY' around, submit your length, help 'GIRL' reach the next planetary body). It's experimental stuff; whereas Katamari and its variants had a defined structure and goals – something that even the most 'sandboxy' games out there have – Noby Noby Boy's sole request is that you submit your length to the greater good.
