Okay, so based on this video evidence it seems unlikely that Steve Jackson is Cthulhu.
The canny will notice that John Kovalic is missing, despite being one of the game’s brains, so perhaps Dork Tower’s Kovalic is also the Great One.
This video is called “Cthulhu Dice Unboxing” but it’s more than that. It’s also a quick demo of the game.
I learn a few things from this; SJ Games cares a lot about retailers and that playing this game simply means learning what all the die rolls mean. Cthulhu dice also tells me we have hardly any sanity and it it all too easy to loose.
