Something interesting but perhaps little known is that there were four unused drink label flavors prepared in the Dreamcast Shenmue game files but never used (the image file was discovered way back by @LanDC). I've written up a post on this, which also includes comparison images of the drink branding differences between What's Shenmue, the Japan release of Shenmue on Dreamcast, and other versions.
