In the late 1980s, Hideo Yoshizawa, Masato Kato, and Keiji Yamagishi worked as part of a small team developing the NES version of Ninja Gaiden. As part of Polygon’s Life in Japan cover (which also features the debut of Yamagishi’s first single from his new album, and the reveal of a game he’s composing music for), I got them together to discuss their memories of it.
