Thanks to the massive success of the original Double Dragon game, Billy and Jimmy Lee have become arcade celebrities! But what was it that made this game such a massive hit? I think you only need to look at the side scrolling beat em ups which came before, and those which came after, to see the great advancement in the genre, and the impressive legacy left. Considered the game which defined the side-scrolling beat 'em up genre, Double Dragon brought together two-player co-op gameplay, use of weapons and interactive backgrounds, plus a (for the time) complicated 3 button control system which enabled new depth of play. Although the genre has been improved upon since, Double Dragon is still great fun today. Other machines made by Taito during the time period Double Dragon was produced include: Daikaiju No Gyakushu - Giant Monster Counterattack, Violent Shooting, Land Sea Air Squad, Great Gurianos, Inspiration Baseball, Arkanoid - Revenge Of Doh, Dr. Toppel Tankentai, Flying Shark, Hishou Same, and Kyuukyoku Tiger
