Video game publisher Data East sued System 3 and Epyx for publishing World Karate Championship, and by extension, International Karate, which was nearly identical to its arcade game, Karate Champ. International Karate used the same coloured fighters, and had the same points system. Initially Data East won the lawsuit, so the game was pulled from retailers shelves, but the decision was appealed to a higher court, who reversed the decision, stating that while the game was similar, it was not identical, and that one game company can not monopolize one entire sport. As a result, Melbourne House did not sue System 3 nor Epyx, as the game The Way of the Exploding Fist is also very similar to both of these games.

A mi się wydaję, że ten utworek ma coś wspólnego z Last Ninja.

The Last Ninja is an action-adventure computer game that was developed and published by System 3 in 1987 for the Commodore 64. As the first in The Last Ninja Series, it set the standard for the unique look and feel for its sequels; Last Ninja 2 (1988), Last Ninja Remix (1990) and Last Ninja 3 (1991).

A w dzisiejszych czasach to jest zupełnie odwrotnie :) Taki Timbaland oraz inni czerpią z twórczości scenowej kopiując całe utwory od scenowych muzyków ;)
