Q. What happens to the World Championships and the AADA?
A. The World Championships were revived at Origins in 2002, but when things slowed down this year, the championships sort of slipped under the radar.
As for the AADA, we will definitely relaunch it, but we're waiting to get Autoduel Times up and running, and we want to get some player input. As of now, there will be no official AADA activities until further notice.
