As always, the holiday season is jam packed with great new releases. For the Wii, one of the biggest co-op titles we're looking forward to is New Super Mario Bros. Wii. A return to the classic platforming gameplay of the well received DS title, NSMB Wii features four player co-op. Another feature of the game, somewhat mysterious, is "Demo Play". Originally, indications indicated that "Demo Play" was "hold left on the D-Pad and the game plays itself for you". Apparently, it's not quite that simple, according to SiliconEra.
