I raised this debate when I joined the forum, it is an interesting one. What is more interesting is the timing. Obviously we have had to wait 14 years already for all this to happen, will the supernatural elements suddenly implemented into the new game after all this time seem even more jarring than had Shenmue 3 been released on the Dreamcast? It could conflict with a lot of peoples nostalgia for the series that's for sure.
I'm also interested to see how the series can maintain is City life structure when you're now being exposed to all these supernatural elements, will Ryo still be able to idly plop money into capsule toy machines?
