Part of my hesitation is indecision. I'm not sure which version to get. There's the original and its blasphemous rituals, as well as a forthcoming revision which redacts the grisly details of Carcosan sorcery. And just this morning I learned about yet another version:
A Bold New Take on the World of Carcosa
First came the controversial original. Then came The Expurgation. But now comes the most shocking Carcosa yet. Can you survive the horror, the madness, the hours of fun and laughter that is....
Carcosa Mad Libs
"Summon the Adjective Ones: This number-hour ritual can be completed only on a adjective related to weather night. The sorcerer must obtain the kind of food found only in ruined kind of shop, plural of the Snake-Men. The sacrifice is a noun number years old with noun. The sorcerer, after partaking of the kind of food, must verb the sacrifice number times, afterwards verb-ing it with its own noun. As it verb-s, 10-100 of the Adjective Ones will verb out of the mists."
(I accept all blame, but this post is probably where I got the idea.)
