Arino previously challenged Fire Emblem: Mystery Of The Emblem when it appeared on the Wii Virtual Console but its release on the Wii U makes for a perfect excuse to double dip.
Given that Arino has played it before you may think he has an advantage but fortunately he has absolutely no memory of playing the game let alone what it even entails. So his challenge to clear Book One: Chapter 3 without the loss of a party member could prove tough.
