 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 called " 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 .
