You would be very hard pressed to name me something that Shenmue did, apart from visuals, that Majora's Mask or Ultima 9 (both released around the same time) didn't do. The closest analogue is Cyberpunk which tried to marry the scope and simulation of GTA with the graphical fidelity of an FPS. Simply put: there is a reason that developers make compromises.
Instead it's easy, Majora's for example didn't have fully voiced characters with a complex dialogue system, nor NPC with routines.
Ultima 9 was one of the chapters to not feature simple npc schedule iirc, and I don't remember every character being fully voiced, but I should check.
Like I said It's hard if not impossible to find a game like Shenmue that do all these things and more at the same time.
Maybe Skyrim is really the only one that comes near, but it still lacks some other things.
Dunkey makes money by being funny, trustworthy, and having very informed opinions of the games he features. He's an entertainer first but that is almost always backed up solid takes. He's not just a troll, basically.
From what I remember, wolf and dunkey takes were far from solid...
The brand power came from those games. The mainline Mario entries are of some of the most consistent quality in the entire industry spanning multiple generations. I would agree that Nintendo (and now From Software) games have a tendency to be graded on a curve (ie: Dark Souls 3 an only really be said to deserve a perfect score if you like Dark Souls) but that's just because the audience is large and consistent with their tastes. Mario games sell tens of millions of copies, so obviously that audience's tastes count for something. Shenmue 3 can't really be said to be "perfect if you like Shenmue" since a sizeable chunk of Shenmue fans dislike it.
Brand power comes from economic power, not from quality. Quality alone hardly sells.
Nintendo is good at selling, the fact the games are also good and consistent is secondary (look at Activision, EA, Ubisoft etc.).
Once you have the brand power you can make the world believe that Mario, Fortnite or Call of duty are the best games around and the standards.
Same with Marvel movies, music, the food industry, basically everything.
