They were originally released for the Dreamcast in 2000 and 2001, and Shenmue II also made its way to Xbox in 2003.
Shenmue I & II re-releases are set to launch sometime this year both physically and digitally worldwide.
The upcoming re-releases will come with several enhancements for current-gen hardware but they're neither full HD remakes nor remasters.
Sega claims its "original feature set" in terms of "jujitsu combat, investigative sleuthing, and RPG elements" will make a comeback in addition to "real-time open worlds that feel truly alive thanks to day-to- night cycles and weather changes, with a population of civilians who follow their own schedules".
Shenmue is a tale of retribution as Ryo Hazuki seeks out to avenge his father's death and attempts to unravel the secrets behind a mysterious artifact known as the Dragon Mirror.
The release comes at a good time for those who've been looking forward to Shenmue III but missed out on the classics.
This collection of two games will be offered with fully scalable screen resolution, a choice between modern and classic control schemes, PC graphics options, an enhanced user interface and even an option to switch between Japanese or English voiceovers.
