According to Gamespot, LucasArts has opted to discontinue its membership to the Entertainment Software Association. Regarding the matter Gamespot got the following response from what they (rather accurately) call "the all-things-Star Wars publisher":
"We can confirm that LucasArts is no longer a member of the ESA," said LucasArts public relations 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. LucasArts will be participating in E3."The news comes in the wake of Activision and Vivendi also ending their ESA memberships. Other than that LucasArts is making Monkey Island 5, this news doesn't actually mean anything specifically (except that maybe publishers don't feel like wasting money), but there ya go.
