Overview:
Double Dragon was one of my personal favorites when it came to NES games. I know all of you are saying that it's not that great. Well, to me it was, the graphics weren't that great and the story was a little shy, but all in all it was a really fun game. At the time there wasn't any other game like it. You had a character that was bad to the bone just in and of himself, and you had tons of cool weapons that you could just pick up along the way. I know I spent countless hours playing this game just trying to get to the end to beat my brother's butt.
