Temporarily abandoning arcade development, Sega AM2 head Yu Suzuki began developing several Saturn-exclusive games, including a role-playing game in the "Virtua Fighter" series. Initially conceived as an obscure prototype "The Old Man and the Peach Tree" and intended to address the flaws of contemporary Japanese RPGs (such as poor non-player character artificial intelligence routines), "Virtua Fighter RPG" evolved into a planned 11-part, 45-hour "revenge epic in the tradition of Chinese cinema", which Suzuki hoped would become the Saturn's killer app. The game was eventually released as "Shenmue" for the Saturn's successor, the Dreamcast.
