My current campaign (3.5e D&D) has somehow taken on a life of its own as Stronghold Building..
I am using Castles and Ruins (an old Rolemaster book) for a bunch of ideas and I even dug some nice stuff out of an old Oriental Companion and Stronghold Builders book for some more. But I am wondering if there are any other books out there that do this kinda thing well?
Or is there even a system out there that revolves predominantly around building a fantasy stronghold/adventure ideas??
This (http://www.amazon.com/Stronghold-Builders-Guidebook-Dungeons-Roleplaying/dp/0786926554) maybe one of the books you are already speaking of. But I think it would be helpful.
