Simon Stevens says:"The number two in Fist of the North Star: Kens Rage 2 is a misleading one. Your initial reaction is that this is a sequel to the original Kens Rage. It’s not until you take the Japanese title of this game that things become clearer.
In Japan the game is called Shin Hokuto Musou which is along the lines of New Fist of the North Star and that is pretty much what this game is. A new version, a re-imagining, a reboot if you will, of Fist of the North Star Kens Rage."
