Outstanding. The most detailed treatment of world building I've seen in a long time. Should be required for all DM's.

Outstanding product. Highly detailed. I especially like the craft rules. A bit complex, but better than what's in the core rules.

Cute. I bought it as a novelty. Don't buy if you're looking for crunchy content.

I really like this system. It has several areas that are not explained as well as I'd like, but that doesn't detract from my like of this product.

Well worth the cost of admission! An excellent guide for building NPC's with realism and depth.
