Downloading now. Will update the OP with interesting info about Shenmue III, Yu Suzuki, and the series at large.
EDIT 1:
Ryan Payton is working on Shenmue III as part of its advisory board. He meets with Yu Suzuki every two months.
EDIT 2:
Yu's passion for creating games has been ignited, he's sleeping at the office, and is full of enthusiasm working on Shenmue III. His game creation style is very different to what Ryan Payton is used to (likely waterfall vs agile development methodology), but says there is "method to the madness".
Ryan Payton keeps prodding and poking about the Saturn Shenmue build. Yu doesn't know where it is.
The team are working hard on making Ryo look like he should.
Yu has been able to hire back a lot of veterans of the series, dating back to the Shenmue Saturn build of the game.
The ambition for Shenmue as a series was to release two games, the first part would be the story of Shenmue + Shenmue II, and the second Shenmue III onwards.
EDIT 3:
Yu and Ryan have had constructive arguments over the game, with Yu pushing revolution and Ryan pushing for evolution. They seem to have met a compromise that works for both, and their overall goal is to make a great game for the fans.
The team are fully dedicated to both the game and Yu, a lot of the people working on the game are there for Yu's benefit as someone they know, love, and respect, Ryan Payton included.
-----
Overall not hugely informative, and the Patreon exclusive content isn't too big on information. The largest bombshell is that Ryan Payton is actually working on the game in a supervisory role.
