A video game controller is provided with at least one rotatable input mechanism such as a “scroll wheel”. The rotatable input mechanism is disposed within the body of the controller but protrudes partially through an aperture to allow a user to rotate the mechanism using a finger or thumb. The rotatable input mechanism may be positioned so that the user may rotate the mechanism while gripping the controller body with the same hand. The input from the rotatable input mechanism may be used to control various software functions, such as video game functions. In some versions the controller comprises a Gamepad style controller with a scroll wheel disposed at the thumb area of one or both of the hand grips.
