This is a good set of METAGAME mechanics, but the description didn't make it clear that these mechanisms are all METAGAME in nature. These mechanics require the players to act as players rather than as their characters. GMs who do not want to erode the suspension of disbelief by rewarding out of character actions will not find this product useful.
My homebrew campaign is too different to use most published FRP resources, but I found many usable NPCs in this product. The personalities have interesting motives and yet are highly adaptable. Also, the included text version allows me to easily copy an NPC into my game prep materials. I also found quite a few usable plot seeds in the bios of the various NPCs. I'm glad that I bought this product.
