I know the current charadesign of kickstarter/famitsu interview are just placeholders but...
Why do not simply import the (superb) original CGIs in powerful Unreal Engine 4 then improve them ? How is it so complicated when the community has achieved similar solid things ? Are the original CGI files lost somewhere or still owned by Sega ?
When you look at :
Shenmue Dreamcast
Shenmue Online
Sonic & Sega All Star Racing
Ryo appears each time to be a different person.
In Shenmue Online trailers, Shenhua was not even recognizable and Lan Di raised a diabolic odd (stupid) smile that did not click with his original personality (notice that Lan Di CGI is used by the kickstarter page).
From a Shenmue III perspective, that does not mean anything but the risk still exists.
I don't want to have the weird feeling to talk to a stranger when it comes to Shenhua or any another familiar person Ryo could find. Accurate charadesign should be as important as gathering the old dubbers.
