Tank! Tank! Tank! may not be what I would have shown off at E3 with innovative new hardware. It's fun in a profoundly goofy, vintage-arcadey way, but it's hardly pushing any new ideas or making any graphical leaps. In fact, it's not even a new game -- it was originally released as an arcade cabinet in 2009.
It doesn't make particularly interesting use of the WiiPad, either. In the demo shown in Nintendo's booth, one player saw the action from behind their own tank, while up to four other players could play on the TV with Wiimotes -- after everyone passed the WiiPad around to snap avatar portraits. The gameplay was the same -- even the view was the same -- just on another screen.
