An entertainment system includes circuitry configured to receive input signals from at least a first input device and a second input device, where each input signal corresponds to a control in one of the input devices, determine whether each input signal is included in a respective control subset allocated to the input device from which the input signal was received, determine if each input signal is an input signal to be utilised based on whether it is included in the respective control subset, treat input signals to be utilised from any of the input devices as input signals from the same single input device, and determine, according to a predetermined control scheme, a process to be executed based on the input signals to be utilised, and where the respective control subsets each comprise at least one control not found in the other control subsets, and the respective control subsets together comprise a full complement of controls for an input device.
