It's been 2 years since the last live challenge but if any game demands such a stage it is Super Mario Maker. Thanks to the contributions of 10,000 avid fans from around the world, Arino will be aiming to 12 user-submitted levels within the allotted 2 hours. Each of the 12 levels follow a particular theme, from the ultra difficult to the ultra easy, but knowing Arino (and past live challenges) things will come right down to the wire.
