That sounds really amazing.
I do have a concern however, and don't wish to sound disrespectful in voicing it... Since I respect everything you're doing. You are certainly a better human being than I.
Basically, I worry for your wallet. I wonder if you've perhaps put up $10k for something you've assumed, rather than something promised to you. That you see your pledge as an investment rather than a donation. I hope you get your wish of course, but I also hope you accept the possibility that you may not get that wish. Yu Suzuki may be unable to make exceptions with the rewards, or allow you to use the credits for promotional purposes. If you're fine with that then fair enough. But if you're not fine with that, then I would recommend reaching out ASAP to seek confirmation.
It certainly doesn't hurt to ask though, so more power to you of course. In fact, I hope he not only grants your request, but even moves you to a brand new reward tier "Be a villager NPC for $10k". (Hmm... that's if it makes sense for other non-chinese villagers to exist in Shenmue III). That would generate more pledges and also open up a new empty slot on the Chi You Men reward too.
(Btw, what's wrong with being a villain in Shenmue? It's just a bit of fun after all. It doesn't reflect on your character in real life
)
