I've kept a lot of the subtle humour in Shadows of Empire, which is WH for Shadowdark. I think the humour is an absolutely essential part of the Old World. It would suck a lot without it IMO, too many fantasy settings take themselves oh-so deadly serious.
I'm planning to change the cover od Deadlands for the PoD to bring it in line with the original Shadow's cover, and the Tower of Hapshut cover about. I have three possinbilities done up. Which do you like best?
