You can see Pikmin's gestures because of the improved visuals.
Pikmin 3's biggest draw will be its "high resolution images through the high-definition graphics," Nintendo's senior managing director Shigeru Miyamoto has told investors.
Asked how Nintendo plans to demonstrate the appeal of Pikmin 3, Miyamoto said: "I don't want to be misconceived, but the biggest draw of this game is the higher-resolution images through the high-definition graphics. You can even see Pikmin's gestures with the graphics.
"We are not going to put asymmetric gameplay in a game if it is unnecessary. In this game, you can see the entire map on Wii U GamePad. The two screens of the TV and Wii U GamePad will let you see what you are doing at any time during your gameplay, which alone is a great evolution for a strategy game."
He added: "As a side note, you can play this game only with Wii U GamePad. If it is hard to imagine what it will be like, maybe you can recall the visuals of the original Pikmin for Nintendo GameCube and imagine how you can play it with the smaller but more detailed screen in your hands. The two control sticks of Wii U GamePad will let you play this game more comfortably and, with a TV screen, the gyro sensor inside Wii Remote Plus will further help your gameplay. Wii U GamePad will give you style variations of playing this game and playing only with Wii U GamePad might be a good experience for you. I hope you will like this game."
Pikmin 3 is scheduled for release in spring/summer.
