Fantasy Games Unlimited (FGU) is a publishing house for tabletop and role-playing games. The company has no in-house design teams and relies on submitted material from outside talent.^[1]

Founded in the summer of 1975 in Jericho, New York^[2] by Scott Bizar, the company's first publications were the wargames Gladiators and Royal Armies of the Hyborean Age. Upon the appearance and popularity of Dungeons & Dragons from TSR, the company turned its attentions to role-playing games, seeking and producing systems from amateurs and freelancers, paying them 10% of the gross receipts.^[3] FGU also copyrighted their games in the name of the designer so that the designer would receive any additional royalties for licensed figurines and other uses.^[3] Rather than focusing on one line and supporting it with supplements, FGU produced a stream of new games. Because of the disparate authors, the rules systems were incompatible. FGU Incorporated published dozens of role-playing games.

Fantasy Games Unlimited won the All Time Best Ancient Medieval Rules for 1979 H.G. Wells Award at Origins 1980 for Chivalry & Sorcery.^[4]

In 1991, Fantasy Games Unlimited Inc. was dissolved as a New York corporation.^[2] Bizar continues to publish in Arizona as a sole proprietorship called Fantasy Games Unlimited.

A new FGU website appeared in July 2006 offering the company's back catalog. It said that new products would be "coming soon". New Aftermath! products appeared in 2008. By 2010, much of the company's back catalog was available. At that time, FGU sought submissions for new adventures for their existing titles, primarily Aftermath!, Space Opera, and Villains and Vigilantes.^[5]
