Here's proof that there's a method to Hideo Kojima's madness -- even if it looks like more madness. The game designer tweeted some pictures of Metal Gear design documents he happened to find while cleaning his shelves. Above is a hand-drawn level map, featuring tons of notes; he also tweeted Codec conversation scripts, with each katakana character hand-written into a grid to fit in the screen (and memory) space.

Kojima also showed off the cover to his design document for "Metal Gear Intruder," which he submitted to Konami in 1986. The proposal was rejected, an occurrence that Kojima probably finds quaintly nostalgic now.
