The Earth Fighter Rayieza (地球戦士ライーザ Chikyū Senshi Raīza) is a role-playing video game developed and published by Enix (currently Square Enix) in 1985 for the NEC PC-8801, FM-7, Sharp X1, and MSX personal computer systems. The game was ported to the Famicom in December, 1987 by Nintendo under the title Ginga no Sannin (銀河の三人). Unlike most other role-playing video games of the period, the game takes place in a sci-fi setting instead of a fantasy world. The game was never released outside Japan.
