Metal Gear is unquestionably one of the greatest video game franchises of all time. The series' tactical espionage action meshes beautifully with Hideo Kojima's utterly wild yet poignant, heartfelt, societally relevant, and thematically sound story. Solid Snake carries a franchise on his back, every arc narratively or thematically tying into the story he kicked off when infiltrating Outer Heaven in Metal Gear for the MSX.
