Yeah but a lot of this is just "maybe" stuff.
Thats the problem with Cyborg Ninjas and I doubt anyone can disagree with me on that one. They always felt too out there even for MGS's standarts. I know, I know, the series had some EXTREMELY out there stuff too but CN never felt like they never went overboard until Rising (MGS4 came dangerously close tho...but it was the finale so maybe it was okay to go all out). CN still were human, they could bleed and die. Their speed just feels cartoonish now whilest before it was FAST but not impossible to see it happening in real life.
It just feels like MGS's future is something out of an over the top cyberpunk with massive nuclear tanks and tiny CNs who can take it out in just a few swings cuz Nano-machines are shamelessly tech-magic at this point.
I really feel like its a sense of flanderization with each entry, feels like everything needed to have more and more. Example, MGS 1 had slightly touches of the supernatural, MGS 2 had a woman actually stopping bullets without her magnetic device (and no, the theory that MGS2 was just a simulation doesnt justify it), MGS 3 had The Sorrow and a borderline river of the dead, MGS 4 had actually very little supernatural in comparison outside of Psycho Mantis deciding to make a cameo (guess its to add to the bleak tone of the game). Same goes for what Nano-machines and CNs, seems like each entry had to have it crazier and crazier to the point it made the series felt less grounded in reality as it on, absolutely climaxing with Rising. Yes, Rising is fun as hell (I personally think its one of Platinum's weakest games but thats a very unpopular opinion) but as a Metal Gear game, it just makes me realize Kojima just stopped caring and decided to go all out on the insanity (as long as it was fun). MGS 5 brought back some level of sanity but not by much with all this talk about parasites and invisibility without a suit and all.
You know, Im almost starting to see why Kojima felt like stopping at 4, he realized the flanderization and he knew it would only get worse with time...
