When you took Ryu to the arcade to play Space Harrier etc there's a well-established if indirect teasing of the fourth wall. After spending in-game money to beat your in-game (in-game) high score, you begin to ask yourself what on earth you are doing.
When Ryu gets the job as the forklift driver this same question leads directly to a beautifully uncomfortable awareness of your self, and of your quest, and of Ryu's.
I don't like the way this writer put it, but the forklifts were at least evolutionary.
