If there’s one thing that’s prevalent in the MGS franchise is that no matter how things end, Snake always has to carry the burden (or eventually have someone take it for him). Kind of like the whole never-ending battle motif that goes on with hatred and more cynical philosophies.
One interesting character that comes back to me is The Boss from MGS3. If anyone recalls her history, she went through hell, and it’s like her existence was nothing more than a lab rat that had to endure through so much. Her whole character and essence clearly wasn’t expounded as much, and I have a feeling Kojima may be connecting that struggle she endured and others that carry it (Naked Snake & Solid Snake for instance).
Another trend I see happening is how the more a person lives, the more they start having to face the reality of their existence, and how being this "savior" for the greater good gets difficult the more you suppress the inner turmoil to the point of self-sabotage. Kojima is that type of guy that will go deep into your psyche when you start analyzing his games a bit further.
With things like trans-humanism, existential crisis, and many other thought-provoking philosophies, I see them all in his games, and this is why I continually enjoy more of his projects. It’s just more chances for me to dive into it, use introspect, and try to formulate what he’s really trying to get at. And the conjecture is only from the trailer of this game and a few other sources.
Imagine the level of cognitive diligence needed to decipher this game when it releases. It’s seriously freaking me out in a good way. And even though I’m not going to revel in the hype that the communal base would create, it’s difficult for me not to start becoming attached in diving deeper into virtual experiential realities like the Metal Gear Solid series.
