Asynchronous multiplayer is definitely the biggest draw of the Wii U. Luigi's Ghost Mansion, thoroughly detailed at the Nintendo E3 press conference, is probably one of the few examples of multiplayer that worked. But I also couldn't help but think it played a bit like Pac-Man Vs. on the Gamecube. That game connected Gamecube and Game Boy Advance in a set-up that's not unlike Wii U. If you're not familiar with it, it's because it didn't take off. Perhaps most disconcerting of all is that New Super Mario Bros U was the laziest showcase of Wii U's capabilities. Mario games have long been a showcase for Nintendo's hardware: Super Mario 64 defined 3D platforming, Super Mario Galaxy convincingly added motion controls, and Super Mario 3D Land proved that 3D doesn't have to be a gimmick. New Super Mario Bros U, however, lets you use the touch screen to add additional platforms to the screen--far from the revolution typically represented by the franchise. If there's one publisher that "gets" the Wii U, it's not Nintendo. Rather, it's Ubisoft. Rayman Legends proved to be the best game for the platform available at the show, with a multi-screen multiplayer experience that took advantage of everything the system had to offer. It's hard to have confidence in the Wii U if Nintendo's own first-party studios can't squeeze the originality seen in this one third-party game.
