When you think of arcade brawlers there are not many names that will top Double Dragon. Technos knew they had a good blend of unique to the competition gameplay and graphics with this one. Sure, there were other brawlers available before Double Dragon but none captured the fan base that this arcade unit did. When brought to the Nintendo Entertainment System this game caused what to happen?
Brawlers are different from one on one fighting games in that you are fighting against a horde of, usually different, enemies. Your move set is also quite limited so that you can focus on taking out the bad guys rather than button combinations to do moves. Likewise, the move sets of the enemies are limited to one or two moves. This keeps the action focused on button mashing and simply surviving the horde.
Double Dragon has spawned two direct arcade sequels and even a spinoff that was more in line with the Street Fighter series. There have been a ton of copycat releases with Streets of Rage and Final Fight being two of the most recognizable.
Companies have kept Double Dragon alive on other platforms such as:
Nintendo Entertainment System
Nintendo Game Boy
Nintendo Game Boy Advance
Sega Master System
Some of the newer (last decade or so) releases feature many improvements. The Game Boy Advance version features new graphics, intermissions, discussion with the bosses and more while keeping a strong link to the original. DotEmu has kept the series alive with their Double Dragon Trilogy release for Android, iPhone and Windows via Steam.
