Great Gaming Crusade: "What do red and blue represent? Red symbolizes hardiness and blue symbolizes vigilance on the American flag. They are the recognizable colors of Marvel Heroes Spiderman and Captain America. Most importantly, they are the colors of the Lee Brothers, the dual protagonists of one of the greatest beat-em-ups in video game history, Double Dragon. While it may not be the best job, Double Dragon certainly retains the hardiness and vigilance found on the classic consoles."
