Yu Suzuki is great at a lot of things, but he is also out of practice or just plain unknowledgeable about other things. I think what SEGA brought to Shenmue 1&2 (not counting the piles of cash) was a structure that marketed games. In the late 90s/early 2000s it was web design, setting up interviews, designing ads, presenting the products with quality renders and logos. But without that, I feel that Shenmue 3 is suffering on the marketing/design end. Programmers, for example, generally suck at other aspects of a game. Like you would not task somebody without graphic design experience to make a press release or design a mock up for cover art. But I feel like that is what is happening. They have a small team and so inexperienced people are being tasked with doing things.
Look at Sonic Mania for how to do it right. They needed new art assets, they hired a talented fan. They needed PR, they utilized what SEGA has. I think Deep Silver could help in some of these areas for Shenmue 3, so it is a wait and see I guess. But still, I don't get these short dev videos and the weird presenter.
