In the past several decades, Kojima’s name has become synonymous with video-game blockbusters.CREDIT PHOTOGRAPH BY JORDAN STRAUSS/INVISION/APOn Friday, October 9th, Hideo Kojima left the Tokyo offices of Konami, the video-game company where he had worked since 1986, for the last time. The departure ceremony, according to one of the hundred or so guests who attended, and who asked that I not use his name, took place at Kojima Productions, the director’s in-house studio, and was “a rather cheerful but also emotional goodbye.” He said that he did not see Konami’s president, Hideki Hayakawa, or its C.E.O., Sadaaki Kaneyoshi, at the party, but some of Kojima’s colleagues from other studios showed up to pay their respects, as did many of the people who worked on his most recent directorial project, Metal Gear Solid V: The Phantom Pain. The game, which takes place in mid-nineteen-eighties Afghanistan and Zaire, made a hundred and seventy-nine million dollars on its launch day, in September—more than the two highest-grossing films of the year so far (“Avengers: Age of Ultron” and “Jurassic World”) combined. In the past several decades, Kojima’s name has become synonymous with such blockbusters, and with the Konami brand itself. His impending resignation had been rumored as early as March, but the fact of it remains startling—as much as if Shigeru Miyamoto, the originator of Donkey Kong and the Mario brothers, left Nintendo.
