“But I only wanted to make MGS4 a window to this; the next step - where you open the window and look at the real world - that's up to the users! I didn't want to exaggerate just to make my story glitter or get coverage on the news, that was not my intention.”

Kojima explained in 2008 that with the themes of Metal Gear Solid 4 the first priority was to provide fun to the users, but that he also wanted to comment on the current world situation; he said he only wanted to make the game a window to that, that the next step—opening the window and looking at the real world—is up to the users, and that he did not want to exaggerate just to make his story glitter or get coverage in the news.
