Shenmue is a 1999 action-adventure game developed by Sega AM2 and published by Sega for the Dreamcast. The player controls martial artist Ryo Hazuki as he sets out in revenge for the murder of his father in 1980s Yokosuka, Japan, exploring an open world, fighting opponents in brawler battles, and encountering quick time events. The environmental detail was considered unprecedented, with numerous interactive objects, a day-and-night system, variable weather effects, non-player characters with daily schedules, and various minigames.
