Vincent Baker or Vincent Baker and sometimes known by the handle lumpley, is a designer of tabletop role playing games and the owner of Lumpley Games which also hosts the archives of The Forge. His most notable games are Dogs in the Vineyard and Apocalypse World.[1][2] Dogs in the Vineyard was the 2004 Indie RPG Game of the Year and won the Innovation Award and was one of three games shortlisted for the 2004 Diana Jones Award[3] and Most Innovative Game.[4][5] Apocalypse World won Game of the Year, Best Support, and Most Innovative game at the 2010 Indie RPG Awards, and was 2011 RPG of the Year at both the Golden Geek Awards and Lucca Comics & Games.[6]


Vincent Baker is the designer of the indie role-playing game Dogs in the Vineyard (2004), one of the first indies to be notably successful, both financially and sociologically.[7] This game was the story of God's Watchdogs, trying to preserve the faithful on the hostile American frontier of the 19th century, and introduced the idea of "say yes or roll".[7] Baker also designed kill puppies for satan, Mechaton, and other indie role-playing games. His publishing imprint is called Lumpley Games. He currently resides in Greenfield, Massachusetts. He is the father of three children and is the husband of Meguey Baker, also a roleplaying game designer.

Baker and Emily Care Boss are attributed as formulating the Lumpley Principle.

Baker maintains a blog-style design journal called anyway..
