You have agency, yes, but what of it? It is just a game. But when a game does this well, you lose track of your manipulation of it, and its manipulation of you, and instead feel inserted so deeply inside the game that your mind, and your feelings, become as seemingly crucial to its operation as its many millions of lines of code. It is the sensation that the game itself is as suddenly, unknowably alive as you are. - Tom Bissell, "Extra Lives - Why Video Games Matter"
