Yesterday, Metal Gear creator Hideo Kojima twitted a picture that shows how the franchise has evolved graphically between Metal Gear Solid in 1998 and the upcoming Metal Gear Solid V (in March).
Although the shown characters aren’t exactly the same, they do share DNA (fans will understand), so it’s a fair example.
