Project Rising Beetle: "The cover of Role Playing Gameside Vol. 2 states that the Medarot video game series has sold more than 3 million units globally. The Japanese magazine will contain a 21-page retrospective on the franchise’s past 17 years in addition to an interview with Medarot series artist Horuma Rin.
Created by Imagineer and Natsume, the Medarot games series started in 1997 on the Nintendo Gameboy. Since then the series has grown to encompass over 20 individual games. The latest entry, Medarot 8, launched on Nintendo 3DS in Japan last August."
