The ESA currently shows 36 member companies on its official web site. However two of the members listed, Eidos Interactive and Realtime Worlds, are no longer active companies. Eidos merged with Square Enix in 2009 and Realtime Worlds shut down operations in 2010 following the disastrous launch and later shut down of its FPSMMO game APB.
The ESA, which owns the annual E3 trade show event as well as the Entertainment Software Ratings Board, lost a number of high profile members in 2008 including Activision, LucasArts and id Software. Hewitt told Big Download today that the ESA has a constant dialog with the industry about bringing in new members as well as perhaps bringing back older ones.
