This is brilliant! But could someone list the names and games of the sprite-avatars shown? Particularly the shooting-only and the jumping+exploring one, I'm pretty sure I got the rest.
Thing's just asking to be a t-shirt design, just needs some cleanup.
Now, not to be picky, but since it's not all Nintendo, what about the primitive behind-the-car and top-down racing games, which are variations on the Frogger idea A-to-B and dodge hits in between? If you were going for iconic humanoid avatars, what about Final Fantasy (Grinding! or Leveling!)?
Of course I only recently read Understanding Comics and still have McCloud's Map of the Comics Universe in mind...
