No no, Kojima had legitimate talent. Had being the keyword there. Metal Gear 1 and 2 and MGS 1-3 are good and interesting games, and you know why? Because despite whatever deep political undertones he wrote in, they're all gloriously hammy like a Hollywood blockbuster. And so a hamfisted monologue on philosophy fits in perfectly since its not any more ridiculous than anything else going on. Solid Snake is what you get when a Japanese guy decides to mash together John Rambo and Snake Plissken into one character. Headband, mullet, stylish weapon that looks better than it really is (FAMAS). Hilariously named villains like Revolver Ocelot and Decoy Octopus. MGS2 has a bomb expert named Fatman for Christ's sake, and we all know exactly what a Japanese guy was connecting him with. MGS3 has a living beehive named The Pain who fires Bullet Bees at you, an electrokinetic Russian who spouts one-liners and has a twink BF he powerbottoms for, and more crosses, double-crosses, and triple-crosses than a Cold War spy novel.
But at some point after MGS3 he decides to get super serial with his writing and instead of bisexual Romanian vampires and Fourth Wall breaking psychics we get.... NANOMACHINES. And when you go from a ridiculous pulp-style action movie universe to something actually serious things just collapse.
