I think to be fair to everyone worldwide who may want this in their collection, we'll break this listing up into regions. North America, South America, Europe. That way collectors from each region can have a native flag in their profile.
You can't select countries from multiple regions anyway as NA uses "U", Europe "E" and Brazil uses "B" in our particular ID system to distinguish titles.
Also there's a good chance other regions will have alternate UPC stickers placed over the original one to suit their own purpose and each variation should have it's own UPC on it's page if applicable.
