As usual, I'm a dumbass. Randy just informed me that the image is in fact directly related to the game at hand. It's horribly obvious now that he pointed it out, too.
That is in fact the case.
Quoted from herg:
You'd have fairly good odds, even without his avatar being in the hint. Not to disparage the other artists, but epthegeek is a machine. I totally petered out when trying to do AMH.
This is my last one for at least a while, probably. Devoting whatever time I have to working on code for Scott's next game these days. It was fun to squeeze one more in so that I ended up on 20 finished.
