I just thought I might chime in here. I am an old school gamer. I have been playing D&D, GURPS, RoleMaster, and WarHammer since the mid 80s.
I got these maps. I printed them out. They look sharp. The most detailed I have ever seen at this scale. Whole cities illustrated as if architect drew them. This set, as the name suggests is focused on "heavily" fortified castles.
I have some high level players in my game world who think they can walk/fly over anything in their way. (Some ride dragons.) They are in for a big surprise! Some of these maps, especially the vault, are laid out to be serious death traps for foolish adventurers and would be thieves. Finally my players might have to think their way past a problem. These maps will save me hours of work. I would strongly recommend them to anyone who likes detail and who has treasure and/or kingdoms in their worlds that they want to defend from all monsters and/or adventurers.
