An apt description comes from a 2009 press release for "House of Game" - http://files.shareholder.com/downloads/ABEA-4UREYL/0x0x402891/0C74635B-1068-4A85-8422-FB5EB2EF7242/DTSI_News_2009_5_22_General_Releases.pdf
"Nerd Poker is a collective of creative individuals from the film, entertainment and game industries who all share a love for video games. Formed in 2006, Nerd Poker began as a group of friends who regularly played games on-line and shared an affinity for identifying progressive entertainment properties. The network has since cultivated a new and unique platform for creative projects, collaboration and business to take place between Hollywood and game creators.
House of Game presented by Nerd Poker will be the first official showcase of its kind that will bring the leading professionals from both Hollywood and video game industries together.
The founding members of Nerd Poker are Kevin Chang, Justin Marks, Ben Fritz and Derek Douglas, with partners Tom Ham, Zach Schiff-Abrams and Ford Gilmore."
