The end of the Sega Mark III's run in Japan coincided with the end of a major period of Japanese history, with its final game shipping just a few weeks after the death of Emperor Hirohito and the advent of a new calendar as the Showa era gave way to the Heisei. Coincidence? Sure. Nevertheless, the end of both the Showa and the ’80s in Japan really did feel like a time of transition and societal change, and these penultimate Mark III exclusives absolutely do come off as something of a time capsule that captures a slice of Showa spirit. In their own way. Sort of.
