Very impressive! When I heard about it, I initially thought, "I see" ... no, I like the games as they are. But when I saw the screenshots, I was impressed. Thanks for what you put into work here and keep Shenmue alive. That Shenmue IV will continue at some point.
I would be extremely happy with only being able to wander the game world of both games in a modern engine. My imagination is running wild with the possibility of living the Shenmue world with 120+ fps, HDR, modern lighting, and even VR.
But having the full interaction of both games feels like a little miracle.
