One thing that been bothering me about a reward from Kickstarter is the one where you can be a Chi You Men character in the game. I always found the idea to be silly what if it distracts from telling a serious story. Is there a limit of how many backers can have their face I'm the game as Chi You Men member?
I don't think it's anything you need to worry about. From the site: "To maintain character setting, body style will be up to Mr. Suzuki." It's just the faces, the bodies and clothing will fit with the game. (And they'll probably adjust the faces by hand to fit) Only 5 people backed the Chi You Men level.
Back in 2015 someone gave the example of the men in black suits that you fight at the top of the yellow head building - most of them didn't look like they were from the region anyway. They bring in top villains from all over... Top villains.
