If you’re looking for something non-stick-like to control your Wii, then you might be interested in the Hori Classic Controller. This one’s all for the Wii and is actually pretty practical when you get right down to it.
On the Hori Classic, you get a 4-button setup that graced the SNES controllers along with two analog joysticks. By combining a bit of the old and the new, you end up with a controller that sports the look of a classic controller with the functionality that suits more modern games.
