Let’s talk good arcade game trivia.
Getting around obscure Japanese regulations, and one of Sega’s best selling games by accident, was created in the 1990s and is called Dottori-Kun.
It is a tiny, budget PCB that was made to comply with new a regulation in Japan that said that arcade cabinets could not be sold bare. Several companies, including Sega, created tiny, low-budget “games” that would be sold with their arcade cabinets. Dottori-Kun was intended to be removed from the cabinet by the arcade owner and replaced with another, better game.
