Ladies and Gentleman, I present to you the first "green" Neo Geo game: Ganryu is made up of 100% recycled materials from older games. Not only did they save on creativity, the also saved on reprocessing the individual pieces by simply slapping past NES-incarnations together like Frankenstein. The final program was hastily dunked in the Graphic and Sound capabilities of the Neo Geo before being released. You might call is a Neo-FrankenNES, or possibly a Neo-Enigma: A NES game masquerading as a Neo Geo game or a Neo Geo game trying really hard to be a NES game. No matter, without further due, I present the autopsy:

PREMISE: Our hero, Musashi, has beaten his great foe, Kojiro. One Month later he has gone to meet his lover (Girlfriend, wife, whatever) Otsu in Kyoto. However, a group of mysterious Ninjas have kidnapped many people in Kyoto, including Otsu (!). Who are the Ninjas, what is their plan, who is behind them, Blah, blah, blah...time for Musashi to fight once more... Blah.
Already you can see this game reeks of Nintendom. But wait, it gets better: There is a second character, "Suzume" who you can select who isn't even mentioned in the documentation. Obviously Visco had better things to do than type "or Suzume" after every Musashi in the Story. Then again, considering all the cut and pasting that went into this game, laziness shouldn't be a surprise [it has been brought to my attention that the title screen eventually mentions Suzume and her story, credit and thanks to Sakura Matsumoto].
