I'd die and never know it was a video game movie

There is a "The Last Starfigter" computer Game.

The OP however, mistakenly thinks the Movie is based on the Game rather the game made from the movie.

(and no I am not talking about the Arcade game featured in the film. I'm talking an actual computer game. Very old. I had it for my Atari 800XL)
