I love speculating about the future of this series, so I'm happy this board exists. Let me extrapolate further on my thoughts:
We have to get away from the trepidation that haunted us for 14 years(going from it's announcement). The Kickstarter was put in place to determine if there was enough interest to continue the series and to build a subsequent team around it.
The original Kickstarter had a goal of $2 million to start with, an astronomical amount for a video game crowdfund. It smashed it in, what, a day or two?
Part of it was hype, but it wasn't hype alone that got it all the way to damn near $7 million by the end.
Not only that, it inevitably spurred Sega to finally acknowledge and release the HD versions, as well as admit they originally planned true remastered(i.e. remade) versions of at least the original Shenmue.
Deep Silver, despite their missteps, saw potential in this series and invested further. Sega had a hand in lending assets, etc.
I like to use Darksiders III as a template for success here. It was a game with a moderate budget and decidedly AA quality, which reviewed all across the spectrum akin to S3.
At roughly 71,000 copies sold on just Steam(console was unknown) it was enough to turn profit and get a sequel greenlit. This was a game without crowdfunding assets and we've no idea what they put into S3(estimates are around 5 or 6 million).
One could extrapolate from their statements that it'd need to sell 100k copies to be a winner, that it did so. To think this game won't sell at *least* that is complete folly, not with this community.
Let's generalize math here(not entirely accurate considering cuts or costs before you get to profit margin) assuming a $60 sale as baseline:
50,000 copies sold: $3,000,000
100,000 copies sold: $6,000,000
250,000 copies sold: $15,000,000
500,000 copies sold: $30,000,000
None of this basic math takes into account costs for advertising, etc but gives you a general idea that even 250,000 yields a nice success. It is also worth noting I believe S3 is a timed exclusive for Sony and will come to Xbox in the next few months, which will further sales.
We look at ourselves here at the Dojo in the context of a bubble. There are far more Shenmue fans out there, not everyone is a member of the Dojo, 500k, etc.
The team is in place, the equipment, the engine, the actors, the community has shown how eager they are. There's no need for further action by the community to fund anything, really.
I fully expect IV to come in the next couple of years.
Yu now has no looming date, no pressure to push something out to the public until it is ready to be shown.
