Delta Green: Countdown (Call of Cthulhu Horror Roleplaying, Modern Era)
By my estimate, COUNTDOWN contains as much material as you would find in four (4) $20 game books.  At $40 it's the most expensive supplement I've ever seen, but it actually pulls its damn weight and earns that price in page after page of tight, startling and extremely well conceived pieces.. . . Upon reading this book over once, then going back and working through it a second time, I pronounce it my first perfect '10'.  This is the most literate, researched, extensive and useful supplement ever written for any role-playing game.The Verdict: Now all the other companies have a new bar to reach for...and you, Gentle Reader, need to go buy this book. --Mike Daisy, Gaming OutpostI swear; sometimes Pagan Publishing refreshes my faith in the gaming industry in a single stroke. Delta Green: Countdown is one of the largest CoC books that I've ever seen; it's about the same size as Horror on the Orient Express, with approximately the same density of information - and, even more importantly, it has the same globe-spanning feel, going from Britain to Russia to Asia to back home. It isn't a campaign, but it does have enough information to run several - the individual sections that comprise the book are worth $20 on their own. Considering that you get seven of them, plus three adventures and a boatload of extra occupations for Delta Green investigators, I'd say that Countdown's $40 price is eminently worth it.  --Darren MacLennan, RPG.net 08/16/99
