If one is referring to the games, Metal Gear was the first Metal Gear game. It was released in 1987 for the MSX2 computer and the Nintendo Entertainment System by Konami. If one is referring to the eponymous Metal Gear mecha, the first one in the series chronology was the Metal Gear TX-55, designed by Dr. Madnar in Outer Heaven in 1995. Prior to the TX-55, there was the Shagohod, as created by Soviet scientist Dr. Sokolov in 1964. This was not a Metal Gear in the traditional sense, as it lacked legs and instead used hovercraft technology and jet propulsion. But it was made to deliver a nuclear payload from any location in the world. However, the original designs for Metal Gear, as imagined by Aleksandr Granin, bore a resemblance to Metal Gear REX and Metal Gear D, although those would not be realized until 2005 and 1998 in the games' chronology, respectively.
A Metal Gear is a bipedal nuclear tank which features in most of the Metal Gear games. The first made Metal Gear is Metal Gear Raxa which was known as an ICBMG, then there was Metal Gear TX-55 and Metal Gear D. The next Metal Gears were Metal Gear Rex and Metal Gear Ray. After those they finally perfected the Metal Gears and made what is codenamed Metal Gear Gekko.

There has been no confirmation of a Metal Gear and Metal Gear 2 remake. They are playable on Metal Gear Solid HD Collection in the Metal Gear Solid 3 portion, but thats the only thing that would be considered a remake right now.
Metal Gear Solid, Metal Gear Solid 2: Sons of Liberty and Metal Gear Solid 3: Snake Eater
They are 2 different genres, metal gear being a stealth game, and medal of honor being a first person shooter, making them hard to compare. But, if you are basing your opinions off of reviews, metal gear is the better game.
It's Snake's nightmare. It is a brief level from the first Metal Gear Solid, where Snake enters Shadow Moses for the first time. It's in the original PlayStation graphics.
