Short answers, pulled from the story.
Eric Goldberg is an American game designer known for tactical combat and role-playing games such as DragonQuest and Paranoia. He worked at Simulations Publications, Incorporated (SPI) before joining West End Games in 1983.
At SPI, Eric Goldberg designed DragonQuest in 1980, which became the largest role-playing game the company ever produced. He also designed the tactical combat game Commando and a second edition of KURSK, also published in 1980.
Eric Goldberg and Greg Costikyan, longtime friends from their years at SPI, approached Dan Gelber about turning Gelber's home-grown role-playing game, which he called Paranoia, into a professional product. Gelber gave them his notes, and the pair developed those notes into a full manuscript.
Paranoia was licensed to West End Games, where Goldberg worked as Vice President of Research and Development starting in 1983. Ken Rolston helped rewrite the rules before West End Games published Paranoia in 1984.
West End Games declared bankruptcy in 1998, and founder Scott Palter resisted returning the rights to Paranoia to Eric Goldberg and Greg Costikyan. A judge ruled in 2000 that the rights belonged to the game's original creators.
In 2019, Eric Goldberg co-founded Playable Worlds together with Raph Koster. The company is currently developing an MMO called Stars Reach.
