RGP Creatures - Bestiary 1 is a collection of 50 fantastic, full-page color illustrations of truly fantastic creatures. The artwork is simply top-notch and I would expect to pay well over $10 for the images alone. But each entry is also accompanied by about a page's worth of text that includes a description of appearance and habits, powers and abilities, and and system neutral game information.
The game information is obviously written with the D20 system in mind, as each creature has the six "classic" attributes and assumes an average human ranges between 3 to 18 in them. But the author was kind enough to include a baseline in other areas, such as protection and damage, that make it pretty easy to convert the number to just about any system.
If I had one comment about the creatures in this book, it would be that they are slightly too fantastic for my tastes. Most of them have some magic powers or supernatural ability, and they would probably work best in a high-magic fantasy campaign. Some of them could work in a space opera type game too as they have a bit of an extraterrestrial or alien feel to them.
Simply put, the creatures in this book are special and would be best used as the center-piece of a fantasy adventure.
