I'm not really sure I get what the writer of that article is trying to say with that example.
Is he suggesting doing away with the detective game elements and open-ended quests? I'm not sure it'd actually be Shenmue without it, and it'd be a fucking travesty if it was replaced with mini-map "run to marker, then run to other marker, then maybe have a fight" quest design. You'd miss out on so much world building through the incidental dialogue that comes with investigating, not to mention never really learning or paying attention to the game world layout.
Take asking in one of the Lucky Charm quarter electronic shops about the Heavens in II. The owner will get the wrong end of the stick and think Ryo is a gang member looking for protection money, and threatens to get Xiuying. Suddenly the reason why the Heavens stick to Aberdeen becomes obvious; they want to steer clear of the martial artists in Wan Chai. It's easy to miss, but the fact it's there is incredible. Shenmue rewards the player for being curious with these little bits and pieces about the world, the story, and the characters.
The way it ends makes me think they're asking for Yakuza with a Shenmue skin, and with no disrespect intended to that series which is great for its own reasons, but I cannot think of anything worse for Shenmue III.
It's a really reductive argument, and ignores a lot of what else builds up Shenmue as a whole, and that (surprise) people can still enjoy Shenmue as-is in 2018.
That's why I'm glad Yu Suzuki is the director and not whoever wrote that article. I don't think he'll do anything that isn't true to his original vision.
