There is not a single video game that opens as profoundly, or as appropriately, as Metal Gear Solid 4: Guns of the Patriots does with Solid Snake’s “War has changed” monologue. In less than five minutes, not only is the game’s tone established, so is a new direction for the franchise as a whole.
With The Boss, and with Metal Gear Solid 3, Kojima recontextualizes the entire Metal Gear narrative to tie into Metal Gear Solid 2’s ending. In that sense, the series also becomes a story that was always leading to an ending like MGS2’s. Metal Gear becomes a perfect circle.
