Ginga no Sannin(JP) is an RPG video game produced by Nintendo for the Famicom. It is a remake of The Earth Fighter Rayieza, a game produced by Enix for Japanese computers.
The player controls a nameable protagonist and Blue as they ride in a pair of robotic combat suits called "Rayeizas". The Rayeizas can be upgraded with equipment found throughout the game. A spellcaster named Rimi can use psychic abilities to help the heroes or damage the enemy.
Very few alterations were made to the game excluding those related to the plot and the overall difficulty level, such as some characters having powers that they were unable to use in the original PC view.
