One difference between the two versions is the passwords.
Not only the generated passwords are different, but the available characters are also different: The question is: Why are the vowels (A,E,I,O,U) missing from the Europe/USA version?
I have read that cars' license plates in some countries don't allow vowels, to avoid swear words.
For example:
https://en.wikipedia.org/wiki/Vehicle_registration_plates_of_the_Netherlands wrote:Nowadays the letters used do not include vowels, so as to avoid profane or obscene language.
https://en.wikipedia.org/wiki/Vehicle_registration_plates_of_Spain wrote:while two-letter combinations ending in the vowels A, E, I and O were also forbidden, apparently to avoid the forming of potentially offensive Spanish words when combined with some province codes
Can this also be the reason behind the difference in PoP?https://en.wikipedia.org/wiki/Vehicle_registration_plates_of_Chile wrote:Vowels are not used in order to prevent profanity,
(Although, to be honest, some digits can be used instead of letters, as in L33T SP34K...)
I also know of a few other games that do this.
I can post screenshots of them if someone is interested.
