Paul Sottosanti's first foray into game design was an unofficial expansion for the popular board game Titan at the age of 12. He got his start in the industry at Wizards of the Coast, where he initially designed cards for the Neopets and Duel Masters trading card games. He then started designing for Magic: the Gathering, and was on the teams for the following expansions: Betrayers of Kamigawa, Ravnica, Planar Chaos, Lorwyn, and Morningtide. He was the lead designer for Morningtide and was responsible for Lorwyn focusing on races and Morningtide focusing on classes. He also contributed playtesting to several Avalon Hill offerings and put together the course booklet for the most recent release of RoboRally. Following that, he moved into the digital realm and was the lead designer for Magic: the Gathering ArtFight and Dungeons & Dragons: Tiny Adventures on Facebook.
After five years at Wizards he transitioned to Maxis and was the systems designer and eventually lead designer for the sci-fi action RPG Darkspore. Shortly after Darkspore's launch he decided to move on and become an independent designer. He is currently working on a variety of board game designs as well as small digital game projects.
