He had big ideas, and didn't give a rats ass what you think. Today's Kojima is all about fanservice, which not only compromises his artistic integrity, but also devalue him as a man desperately appealing to the times. MGSV will quickly be forgotten in a few years, MGS1 & 2 won't.
I honestly think V is already forgotten. You don't even hear about it anymore, which started around November ish. You're spot on about fan service, which essentially started in MGS4 answering all of MGS2's questions as literal. Just look at Arsenal Gear's "******." It completely and utterly doesn't make sense, but did it anyway. That's the Kojima I want back. Whatever he does for Sony... I just don't care really. He's in his phase of loving the smell of his own farts.
