John Carpenter actually noted Kojima's obvious influence once and stated that he was "flattered" since he is also a fan of Kojima's (Carpenter plays a lot of video games IRL).
The thing what I like about Kojima is the fact that he's going through so many different influences and mixes them together in a concoction with his own flavouring. It's really not all about how original a story is, it is the way in which a story is told that makes the difference and I loved Kojima's storytelling style in his earlier work. It really felt like it was his passion and straight from the heart and mind of a movie maniac. I love that and hope that's what we get out of him making something original again.
There's very few games that were more immersive for me other than Snatcher, MGS1 and MGS2. The original Metal Gear Solid honestly felt so fresh at the time of its release, people may not appreciate it nowadays since there's been sooooo many cinematic games since, but back then, what an amazing experience that was. It changed how I viewed games forever.
