Marc William Miller is a wargame and role-playing game designer and author.
Early career
After serving in the U.S. Army, Miller continued his studies at Illinois State University in 1972 under the G.I. Bill. There he joined the ISU Game Club, created by Rich Banner and Frank Chadwick.
In 1977, GDW released Pearl Harbor, a game by John Prados that turned out to have serious issues. Miller was brought in to redevelop the rules, resulting in a much improved second edition released in 1979 that received good critical reception.
Miller, Chadwick, Harshman, and Wiseman designed Traveller, which was published in 1977 by GDW. His novel Agent of the Imperium was nominated for the Dragon Awards in 2016.
