"When I was doing 2nd edition Warhammer Fantasy Roleplay, for example, there were certain elements that I felt had to be carried over from first edition to make it WFRP. While you can certainly see my design principles at work in the game, if I started it from scratch I may have taken a different approach in some areas. It was really important to get the feel of WFRP right though. I mean, I could have just thrown out 1st edition and done my own thing, but there would have been little point in calling it WFRP then.
