Makers and owners of video games, pinball machines, kiddie rides, compact-disc jukeboxes and other coin-operated amusements are holding their annual meeting this week at the Anaheim Convention Center. This is the 40th year of the convention, which is organized by the Amusement & Music Operators Assn., based in Chicago. New this year: several virtual reality games. The show, which runs through Saturday, is not open to the public.
