I am a huge fan of Kojima. I think he shut down a lot of criticism with the Metal Gear series. Those games are master pieces. I read somewhere last week that he had to create a stealth based game with the original Metal Gear because the hardware was not capable of supporting a sufficient gun fight between two characters on the screen.
Many people thought that it was insane and that no one would play it...ahem.
Kojima is fraykin genius. MGS 3 is a proper jungle survival game. What other game does your character have to hunt to eat or perform procedures on himself if injured. That game has it all.
