Ninja Gaiden began as a Tecmo action game in the late 1980s, first in arcades and then on home consoles, where short musical stings marked victories and stage completions. The series became known for its fast, difficult combat and its distinctive chiptune soundtrack, and clips of its victory sounds have circulated for years among retro gaming fans. Today creators reuse the fanfare as shorthand for beating something hard, because its retro sound instantly reads as an old-school win to viewers who grew up with the games.
