A user input device , comprising: a housing that defines an internal cavity of the user input device and includes an aperture ; a joystick assembly that is disposed within the internal cavity, the joystick assembly comprising a tilt-able post and being operable to generate an analog input control signal based on a position of the tilt-able post in relation to a default position; a thumbstick cap that is mounted through the aperture to an end of the tilt-able post ; and an adjustment mechanism configured to enable a tilt tension of the tilt-able post to be changed, wherein the adjustment mechanism comprises: a pin that resides in a post opening that extends through the tilt-able post along an axis of the tilt-able post, the pin having opposing first and second ends, and having a flange positioned between the first and second ends that extends around at least a portion of a circumference of the pin; and a spring that coils around the circumference of the pin and is compressed between the flange and a base portion of the tilt-able post; the pin being movable along the post axis through the post opening from a first position to at least one additional position along the post axis to change the compression of the spring, and thereby modify the tilt tension of the tilt-able post. a housing that defines an internal cavity of the user input device and includes an aperture ; a joystick assembly that is disposed within the internal cavity, the joystick assembly comprising a tilt-able post and being operable to generate an analog input control signal based on a position of the tilt-able post in relation to a default position; a thumbstick cap that is mounted through the aperture to an end of the tilt-able post ; and an adjustment mechanism configured to enable a tilt tension of the tilt-able post to be changed, wherein the adjustment mechanism comprises: a pin that resides in a post opening that extends through the tilt-able post along an axis of the tilt-able post, the pin having opposing first and second ends, and having a flange positioned between the first and second ends that extends around at least a portion of a circumference of the pin; and a spring that coils around the circumference of the pin and is compressed between the flange and a base portion of the tilt-able post; the pin being movable along the post axis through the post opening from a first position to at least one additional position along the post axis to change the compression of the spring, and thereby modify the tilt tension of the tilt-able post. a pin that resides in a post opening that extends through the tilt-able post along an axis of the tilt-able post, the pin having opposing first and second ends, and having a flange positioned between the first and second ends that extends around at least a portion of a circumference of the pin; and a spring that coils around the circumference of the pin and is compressed between the flange and a base portion of the tilt-able post; the pin being movable along the post axis through the post opening from a first position to at least one additional position along the post axis to change the compression of the spring, and thereby modify the tilt tension of the tilt-able post. <EOS>
