I used to actively design roleplaying games, and medieval agricultural yields have been a passion of mine since the original Chivalry & Sorcery Sourceboook (1978)[1]. In particular, in the 1990s I wanted to understand Domesday Book in detail to project what a medieval farm would look like as part of Pendragon roleplaying game, which I owned the rights to for a time when I had a company called Green Knight Publishing. The game is back with Chaosium these days, and I remain a fan of the RPG.
