I played Shenmue 3 back when it was released, I've had time to let the experience sink in and what remains in my memory is the following.
I enjoyed Shenmue 3.
I enjoyed the slow pace of the game, gathering herbs, the fighting system, setting some time each day to train diligently, exploring the locations, etc.
My expectations were reasonable for a sequel that would have way less budget and man-power. I was not disappointed by playing the game. It was a relaxing time.
The food system didn't work, but could be circumvented easily so it didn't get in the way.
I didn't like how Shenhua feels much more distant once you arrive at Niaowu.
The story had some shaky moments.
But the true issue for me was the lacklustre ending, it was too short, too rushed, lacking in interaction between the most important characters in this chapter, didn't explain anything, was little in the way of a conclusion for this chapter and didn't make me feel hyped for a next entry.
An ending can break a game, but in this case it didn't ruin it for me, while the ending was disappointing, I still cherish the experience I had with Shenmue 3.
I was actually surprised to see so many people disliking the game.
