What can be said about this product? The original Tomes of Horrors were all great products that featured and number of "old school" monsters from previous editions of the game all under the OGL. It even had a breif "tutorial" on how to add these beasties to your own products.
Now those very same monsters are back in one huge book "updated" to Swords & Wizardry stats. Nearly 700 monsters, all ready for your game. In addition to art and stat blocks for every monster there is also an adventure hook for each one.
The monsters have been "scaled down" to fit the S&W rules better.
One minor nit-pick. The original art is used (which I am happy about) but in their efforts to redo the layout sometimes that art is reduced in size (making it hard to see) and other times the art is placed over some text. Not often mind you and not enough for me to downgrade this product.
Now what I would like to have is one "Ultimate Tome of Horrors" that has the Pathfinder and S&W stats together with the plot hooks.
