What's the meaning of the icons on the backside of Wii U games?

Question

While building a database of Wii U games, I am struggling with the meaning of the hardware requirement symbols on the backside of the game. I can keep apart the symbols e.g. for Wiimote, Wii U Gamepad, USB stick and headset, but there are a lot of other symbols I don't understand.

Is there a comprehensive list with possible Wii U input methods and accessoires, including the icons which can be found on a game's backside?

Answer 1

I couldn't find a list of those icons, so for now, I'm going to describe the ones from the screenshots provided in the comments.

From left to right:

• Obviously the Wii U GamePad: the main controller for the Wii U.
• The Wii U Pro Controller: a more traditional controller, similar to the Xbox 360 controller.
• The Wii Remote aka Wiimote: the main controller for the Wii.
• The Nunchuck: an add-on for the Wiimote, adding an analog stick, two shoulder buttons and another accelerometer.
• The Classic Controller: an add-on for the Wiimote that acts as a traditional controller.
• Possibly the PDP headset, but it could also refer to headsets in general.

Last icon:

• The Wii Wheel: Actually, it's just a piece of plastic to make the Wiimote feel like a wheel.
