"Metal Gear[a] is an overhead military action-adventure video game originally released in 1987 by Konami for the MSX2 computer in Japan and parts of Europe. Considered the game to popularize the stealth game genre, it was the first video game to be fully developed by Hideo Kojima, who would go on to direct most of the games in the Metal Gear series.[3] A reworked port of the game was released for the Famicom a few months later, which later saw release in international markets for the NES over the following two years;
this version was developed without Kojima's involvement and features drastically altered level designs, among other changes." -
