Thanks again Ana for responding. You too sarahandus. I read through the thread you linked and it seems no one there had much to offer and a "techie" never dropped in to contribute. This was for another Viva game Alter Ego.
I had searched some for more info about those letters as how they pertain to an actual game and couldn't find much.
If as you say sara, from what you derived from that small wiki paragraph, that is what it is then why aren't all the editions of a game from the same company labeled with that? I would still think there may be some difference between them. Thanks again for the help.
