Gamings Best Ninjas Have A Night On The Town In This Bad Ass Art

I can't even begin to hit on all the ninjas of gaming you see in this picture. Just off the top of my head I see a couple Mortal Kombat characters, Dead or Alive, Ninja Gaiden, and Metal Gear Solid! Whoever they're going after is screwed! Can you name everyone in this bad ass art by Lonefirewarrior?
