*Whew*, this took longer than any other strip I've ever done, BY FAR. I drew each character from scratch, save Hobbes, and even he took awhile to edit and pose correctly once I had him in line art form.
The strips/games represented (from left to right, hopefully I get this correct) are: Rage comic, Order of the Stick, Xiao xiao, Rick the Stick, Stickman and Cube, Fleatoon, Cyanide and Happiness, Invisible Bread, Pivot, xkcd, Hyperbole and a Half, Calvin and Hobbes, and Prolly Not Funny. I had a few more which just wouldn't fit.
Happy Halloween, from Three People Get It.
