Needs to change the functionality of the buttons, triggers and sticks based on whether you are walking, driving, flying, scrolling or looking at the map. Need to be able to assign the full allowable set of commands. There are 16 buttons on the controller, not including moving moving and looking around with the sticks. Double clicking makes it 32. Add in using a buttons to bring up a menu to scroll through and assigning the commands based on what the person is doing at the time (driving, flying, walking, looking at the map, scrolling etc.), each of which allows for an entirely new set of commands to be assigned, puts the number in the thousands.
