It's clear that Pikmin 3 was not designed with the GamePad in mind. Even in our review guide, Nintendo recommends playing with the Wii Remote and Nunchuck. Controlling the virtual cursor becomes much easier the Wii Remote, and alleviates many of the camera control issues you may face when playing with just the GamePad or Pro Controller. Given how ideally suited a touch screen is for the RTS genre, it's disappointing to see Nintendo approach the GamePad with so little ingenuity. In fact, taking advantage of the second screen might have offered the "freshness" that's missing from Pikmin's return from dormancy. At the end of the day, Pikmin 3 is more of the same--a great game that happens to be on Wii U. However, what Nintendo needs most of all right now is a great Wii U game. 
Too bad they're all going to die
