Comrade, Prepare to Play for the Glorification of the StateAn East German arcade machine manufactured in the mid-1980's has been recovered. As you can imagine, government-approved arcade machines were exceedingly rare--it was apparently the only one ever authorized. It included six different games, all of which were knockoffs of an equivalent game in the West.
