Hey hey, let's not bag on the MGS. I just finished the 3rd one. Waiting for the 4th one on the PS3.... *drools*
Bless those Japanese guys who created Sony, Nintendo, Square-Enix, Konami, and just about every gaming software company out there.
As for the Cold War topic, I don't think any of the American or Soviet weapons would have ever became really feasible on a real battle. The technology they dreamt of was just out of reach for those times. It's like us right now thinking of warp-speed starships. Sure, we can theorize but we are faaaar from designing a ship capable of that. Although the satellite weaponry idea would be sort of plausible, but the accuracy or firepower would have been questionable. I remember reading several news articles about declassified Cold War-era documents that stated that most of the Soviet missiles and "weaponry" they showed off were mere decoys. In other words, the number of real weapons/missiles they had were grossly exaggerated. They only wanted to make the US think that they had weapons so that the US would think twice about attacking them.
