A very revolutionary game. Discs of Tron pits Tron
verses Sark in a game that is best described as 3-d "Combat"
raquetball.
Discs of Tron features good use of the joystick/paddle
combination, excellent graphics, and very cool game design.
As a side note, this is the only game I know of that overlayed
the graphics over a hand drawn picture (of the Game Grid).
