Hideo Kojima! The name basically means Konami and Metal Gear. He has been the public face and figure of the company for the last ten years, and in doing so, he has made the Metal Gear series one of the most successful game franchises of all time.
That public presence for Hideo Kojima grew after he signed up for Twitter in 2010, and he started tweeting all aspects of his life, from development pictures of his latest games, such as Metal Gear Solid V: The Phantom Pain, his trips to games and awards shows, like E3 and TGS, trips to other developers, such as Kojima Productions LA, and even pictures of his daily life in Japan, such as views of Tokyo at sunset and the meals he ate every day.
Both fans of Hideo Kojima and the Metal Gear series grew to love the public figure that Hideo Kojima had become, as he was so open with the fans about his games, but at the same time keeping enough back to keep them interested and guessing about what he would be talking about next. On top of that, Hideo Kojima has grown to love trolling his fans with absolutely outrageous but completely hilarious jokes that has basically made fans keep guessing where things will go next.
