While immersed in my 15mm craze years ago, the Demonworld line of fantasy miniatures were customarily extolled. In researching them, I also discovered the Hobby Products campaign game Empires (a knockoff of GWs Mighty Empires). Anyway, I have yet to acquire any Demonworld miniatures, but I did get the Empires box set, from eBay, I think.
The included game board is heavy cardstock and there are card “counters” one could use for minis. At some point in my research on the game, and acquiring resources for campaign games, I downloaded pdfs of this and a few other Empires boards. They are somewhat modular, and thus can be combined.
As with Armada, and as will become a running theme, I haven’t played these rules either. The book is a dry read; perhaps the game would be fun. I am planning soon to begin collecting Demonworld minis before they get discontinued.
