This book collects the final projects created by students in the Game Design Workshop course during the Fall of 2020. The projects produced in the class are all playable systems—designed over 7 weeks, culminating in live multiplayer play sessions that were ‘run’ by the game creators on the online virtual tabletop platform Roll20 (roll20.net). Each game creator performed the role of Game Master (AKA Dungeon Master or Judge) for their game—a difficult task combining acting, explaining rules, improvisation, and controlling the nonplayer game tokens and map elements as they are encountered.
