Also MGS.

The latter half of the Metal Gear video game series published by Konami and produced by rockstar director Hideo Kojima. Includes Metal Gear Solid (PSOne, later remade and published on the Gamecube as Metal Gear Solid: The Twin Snakes), Metal Gear Solid 2: Sons of Liberty (PS2, later rereleased with extra non-story missions on the PS2 and Xbox as Metal Gear Solid 2: Substance), and Metal Gear Solid 3: Snake Eater (PS2).

The first MGS innovated a style of gameplay that would eventually lead to the explosion of the stealth genre (which would include well-noted titles such as Splinter Cell), which focused on avoiding enemies through stealth rather than engaging them in combat. MGS2 further developed the gameplay of its predecessor by adding new ways of navigating environments, as well as the ability to aim weapons in a first-person view.

All titles in the series are extremely story-heavy, and are notable for their graphic quality which is often years ahead of most other games, well-directed cutscenes, exceptional voice acting, and controversial postmodern concepts.

The series is generally regarded as one of the best ever produced in video gaming, and competes with efforts such as Ico as the most artistically relevent title to come out of the fledgeling genre.

A Metal Gear game loved by some fans but not all, mostly due to the game not surrounding Snake, but surrounding a badass cyborg samurai dude with white hair who somehow stops time to slice you into tiny bits while very loud and good music plays in your ears.
Person 1: "Metal Gear Rising sucks. It's a complete change and the protagonist is not even that cool."

Person 2: "Okay, but can you beat the games OST?"

Person 1: "Fuck."

An extra Metal Gear name, making Jack "Raiden" the main character. He is also known as, "The Badass Ninja Guy From 2, 3, and 4". He is a cyborg.

This game is getting all true Metal Gear fans excited, because of the shocking ending of Metal Gear 4.
MG Fan 1: DUDE, DID YOU HEAR ABOUT Metal Gear: Rising!?!?!??!?!
MG Fan 2: YEAH, I'M SO FUCKING EXCITED!!!
MG Fan 3: I came.
