According to our 11-year-old Nintendo research intern, Super Smash Bros. (for the 3DS and WiiU, not the DS) is pretty great. We waited for about 20 minutes to play the 6-minute demo–totally worth it for the exclusive “fight towel” swag–and discovered that the Wii Fit Trainer is no match for the combined power of Luigi, Bowser, and Greninja. The game releases on 10/3.
