See, the problems I have with the whole language thing is A, what exactly is the purpose of getting rid of certain languages, and B, the thought that you could activate a virus, or whatever the hell it was, by speaking a certain language. It was just plain stupid to me. The nano machines in MGS4 might be way ahead of their time, but they're not completely unreasonable in their application. The virus in MGS V is just silly. And what would really be accomplished by eliminating a language, as well as most, if not all, who speak it? You're not creating a unified world, you are destroying massive parts of it, to leave a certain segment behind. And why did Skullface want to do this in the first place? I also never understood what Zero's objective was. He trained Paz and sent her on her mission, but he also kept Big Boss safe after the events in Cuba.
And we've been over this before, but wow, Skullface is such an underused and boring antagonist. The ride in the 4X4 with him was super awkward, and made zero sense. Big Boss is like the worst operator ever, literally putting his life at the mercy of the incompetence of whoever has a gun.
The metallic archaea was the stuff that was supposed to disable the nuclear bombs that Skullface sold, right? I don't even know how his dealings with various PMC's fit into the storyline. Nor do I understand why he sold equipment such as Walker Gears to PMC's in Africa, or why the Soviets were working with him, and did nothing when he started selling off their equipment, or killing Soviet soldiers.
Quiet is an enigma to me as well. She is kept alive by the virus thingy and her thirst for revenge. What revenge? On Big Boss? Why? She tried to kill him when she was part of Cipher, and he defended himself. Hardly seems fair to hold a grudge on him after that. The whole photosynthesis was also just plain stupid, not to mention I don't think it was ever explained why only she had that ability, or flaw, depending on how you look at it. Considering the things she'd done, without really having done anything to redeem herself, I felt no pity for her towards the end of the game.
In short, I don't think I ahve a reasonable grasp on the story, because it was poorly told. A lot of info is in the casette tapes, but for the most part, I'm doing other things while listening to them, which means I'm no doubt missing some important stuff. MGS4 might have had long cut scenes, but for me, most of the dialogue and the movie like excecution of them, held my interest enough for me to fully understand the story and the universe. Dispite it being my very first MGS game.
