If you really love the game, nothing compares to the original Joystick.
Sure the WICO Command will give you the Button to fire, but when it come to the LIGHT CYCLE, you need that Joystick to act like a 4-way and not 8-way (this was the special thing about the TRON Joystick).
But if you just want to play it, the WICO or any other Joy with Button will do along with a SPINNER.
