D Software, the makers of legendary games like Doom and Castle Wolfenstein, has declined to renew its membership in the Entertainment Software Association.

This adds to a long list of big-name game studios like Activision/Vivendi (which includes Blizzard Entertainment) and LucasArts that have also cancelled their memberships from the troubled video game group.

The ESA serves as a lobbying group for the video game industry and also runs the E3 Media & Business Summit – which is the ressurected E3 Expo.
