A good chunk of both MGS 1+2's cut scenes are stock footage from the military. The core theme of 1 is about the government doing nefarious testing on special forces soldiers to make them in the image of history's greatest mercenary then they revolt and hold washington hostage with a nuclear mech.

You have to be thicker than a bowl of oatmeal not to pick up on the politics MGS was putting down. The game was influential in a young me getting into politics because I was intrigued by nuclear weapons and their implications, I learned about the START Treaty from this game.
