I'm finding it hard to believe that there are people who would find answers to any of the fundamental questions at the root of philosophy in a video game, but then some people are able to find the meaning of life on the head of a pin, so far be it for me to tell anyone what they gain from any experience.
The intent of the MGS games, as is that case with any game, is first and foremost to entertain.
Anything the player chooses to take from the experience beyond that is entirely on that individual.
I seem to recall Kojima saying something along those lines in an interview: that MGS4 is to entertain the player. It's not meant to be didactic. It's not telling anyone what to think. He's not trying to predict the future. There are moral overtones, typically expressed by the script writers speaking through characters, but this is no different from any form of media conveying any semblance of a message, big or small.
I recently finished the game so now I can go back and watch the perspectives BR-D without worrying about any spoilers, but I'm pretty sure there's nothing in there that has Kojima stating he's trying to present any sort of "truth" in an attempt to tell anyone how to think.
It's entertainment. Take from it what you will.
