The good: Cudos to C7 for going back to the original setting from 1st ed and for the great artwork.
The bad: An overly complicated and poorly explained edition of WFRP.
I wish 4th ed could have been a modern take on Warhammer Fantasy Roleplay that could have included many of the great things in roleplay that has developed since the beginning of this millenium. Instead this comes across as an even more complicated oldschool version of WFRP with very little guidance in the book as to how the rules should work in play.
Who should buy: Fans that must have everyhing WFRP related or those who like to tinker with houseruling of WFRP.
Who should not buy: People new to roleplay or those looking for a modern roleplay system.
