Yes, I have to admit other than a single line this review doesn't seem interested in discussing whether I should buy this adventure as someone who owns the original two books.
i want to play CoC D20, but there are no players here. so, is there any online/ IRC campaings going on? let me know. im not bothered about whether im DM or player - ill go for both TBH.
