Print means the language in printed materials like instructions. VO mean the audio language spoken in the game. This list indicated the languages that come included with copies.
PC users on GOG and Steam will be able to download additional language packs if they choose. If any countries are missing, please let us know and we will try to get the info on the missing countries. There is no difference between platforms when it comes to language. These apply to all platforms PC, Xbox One and PlayStation 4. I have created a listing of which countries carry which languages.
Usually because they are interested in ordering a copy from a 'foreign' (a country outside where they live) country or they live in a 'foreign' (a country they are not from) country and want to get a copy with their native language. I have seen people asking questions about which languages come with which versions of the game.
