Universal (a video game manufacturer unrelated to the Hollywood studio of the same name) introduces a cute arcade action game, Mr. Do!, casting players as a clown with a deadly weapon to use against underground monsters. Mr. Do! leads a revolution in the video game industry not with its game play, but with its form factor: it is sold as a conversion kit which can be plugged into a generic arcade cabinet, a concept which could potentially save arcade operators thousands of dollars by sparing them the expense of having to purchase an entire new machine to swap out games.
