Established in 1968 as a wargames convention by Gary Gygax, who later co-created Dungeons & Dragons, Gen Con was first held in Lake Geneva, Wisconsin. The convention's location moved between various sites in Wisconsin from 1972 to 1984 before becoming fixed in Milwaukee, Wisconsin in 1985, where it remained until moving to its present location, Indianapolis, Indiana in 2003. Other Gen Con conventions have been held sporadically in various locations around the United States, as well as internationally.
