And the EU will split to 2 parts: west EU (old EU) and central-east EU (aka Intermarium), lol.
Seriously speaking, my idea for that is that I want to do another group of categories, which will contain grouping by: country (as it is now), continent, organization. In the last type of grouping I would use something like this:
Not sure however, how much up to date is that map xD
I didn't count EU as a country not for a political or an ideological reason, but simply because it's not a country and the map uses countries. I could, of course, highlight every country, which belongs to the EU on the map, but probably not all players would like it. However, if I will be doing the grouping by organization, then I will count both people who have set their country as EU and people from countries that belong to the EU. And even then there still be the Others category simply because not all countries belong to any internationally significant organization and some people didn't choose any country. Also, not sure, if all countries are covered in both EW flags set and on the map.
So, simply speaking, there are some technical limitations and I had to made some choices.
And even if I'd like to group people by IP, I can't do it, because I don't have direct access to people's IPs (only EW has; I could only (probably) check IPs of people, who have the script installed). But even then, there are proxies and anonimization networks (like Thor), so the stats will never be 100% accurate, just an approximation.
