Frog God Games, a small gaming outfit, has taken upon themselves to be bitchin' and release all three of Necromancer Games Tome of Horror volumes in one gigantic book (damn near 800 pages!) full of horrible things to make a RPG gamers life hell....next to running out of Dew and Cheetos.
Yeah, its the three supplementary monster books from the D&D 3.0/3.5 age. And yes it's now converted into PFRPG rules. And when I preordered the unlimited version (2nd printing, different cover, no further changes) it came with a PDF copy as well and I spent literally 3 hours reading through it. I can't believe what was included in it and I can't wait to unleash some of this stuff into that Dark Souls conversion I'm attempting.
For the old and crusty gorgnards who read this FGG has a large book of monsters that have a very 1st Ed D&D feel. The relentless, death dealing, horrors that you wretched bastards kept unleashing onto your newbie gamer groups.....<starts sobbing uncontrollably>
Anyways, its good stuff. And for those who know my disdain for reading PDF's it must have had some good stuff within to keep me staring at a computer screen for 3 hours and not getting paid for it.
