Shenmue 3 was already announced at E3 but one committed fan has remade parts of the original game in HD. The Dojo and Hazuki Residence have been redone in HD using Unreal Engine 4. As you would expect from the Unreal engine, it comes with a remarkable amount of detail.
Shenmue was originally released for the Sega Dreamcast in 1999 (Japan) and 2000 (US/EU). It was one of the most expensive games ever made with an estimated budget exceeding $50 million. The game sold 1.2 million copies but was unable to recoup the cost of development.
