My first published design is a 2-player strategic block wargame on the English Civil War called This War Without an Enemy. I am currently co-designing a 2-player strategic wargame on the Napoleonic Wars and co-developing a 2-player operational wargame on the Normandy landings in 1944. Do you detect a theme here?
My next solo design is likely to be a 2-player deck-building game called The Anarchy on the political and military struggle between the Empress Matilda and King Stephen. Breaking with my tradition, it won't be a wargame.
