Gameslave was a pejorative term used on a planet to describe someone who spent too much time engaged in computer games.
As a punishment, excessive users were forced to engage in a giant pinball game whilst encapsulated in one of the balls. The crowd of spectators were allowed to decide the players' fates based on their performances in the game. Gameslaves included Joyce Tick and Track R Ball. (COMIC: Pinball Wizard)
