Joystiq carries confirmation from the Entertainment Software Association that publisher LucasArts is no longer a member of the organization. The company joins Activision and Vivendi as the latest to break from the ESA, a group dedicated to the business and public affairs needs of game developers and publishers.

However, unlike others, LucasArts will still be present in the coming E3 Media and Business Summit this July.

“We can confirm that LucasArts is no longer a member of the ESA,” said LucasArts PR director Margaret Grohne. “As a company we are still committed to bringing consumers the best interactive experience possible and support the ESA’s mission in the industry.”

No reason was provided for the departure.
