The original million-coin challenge: Wario Land!
As Japan wriggles in the grip of gold fever (both via the race for medals in the London Olympics and the race for coins in the just-released New Super Mario Bros. 2), I can't help but try and shake the onset of this very same disease in me, committed as I am to my American-version 3DS system. Like the common cold, I feel it creeping up on me, little by little.
