Mark McLaughlin designed a game of the Thirty Years War called “Holy Roman Empire” or HRE for short. I’ve never played it but I do have a copy. It looks a good basis for a miniatures campaign so I’ve summarised some of the features which I think make it interesting. I found the material on Board Game Geek: Holy Roman Empire useful when looking at the game.
The Holy Roman Empire (HRE) board game by Mark McLaughlin has elements, including a great map, which make it a good basis for a miniatures campaign. A Mapless Campaign is simple to run and encourages on-going participation by the players. This is my stab at combining the two.
