I think I played my last D&D session more than 20 years ago, and never went further than the good'old "Advanced" set of rules, and witnessed the infamous "OGL war" from distance. But I was asked to make a strip by some cultists.
Art G., a very mad Cultist, carved the Great Cthulhoo from the UVoD Munchkin extension on his own flesh! May the Great Old Ones have mercy on his soul.
It's visible on the Guest Art Gallery.
