By Crom, this is a great deal! At first, I was a little skeptical and left a request for more information after reader what others had posted on this collection. Within just a day or two, the publisher got right back to me and had confirmed everything was in working order, so I jumped in on the purchase as a surprise for my players. The wealth information at my fingertips makes me feel as though I've stumbled upon an ancient library of forgotten lore, buried for millenia beneath the jungles of The Black Coast. The quality of every page is marvelous and I have yet to encounter any trouble with the files themselves. Aside from a few of the grammatical and spelling errors one would expect of scribes being pressured under pain of flogging, the charts, tables, and various informative sections are expertly constructed while the new mechanics, creature encounters, items, and sorcerous abilities seem perfectly balanced with the game and its many new archetypes. I have yet to delve into the ancient texts pre-dating the 2d20 system, but a conversion guide is available for those bold historians who wish to take their learning a step further without the need to first become masters of the old ways of the d20 era. The fact that these manuscripts and guides remain at all is a marvel on its own, but their inclusion in this bundle makes for an amazing deal that is more tempting than the fabled Heart of the Elephant. With all that I own now, thinking that there will be future additions at no cost has me thrilled to face down the horrors of the Hyborian Age with a band of dog brothers and sisters, eager to bloody the sands at our feet. Do not pass up this wonderful opportunity!
