As per a request by nuclear-kid I have scientifically calculated using stats the ranking of nations as it is now. Based on numbers alone, and this process does have some errors, here's what we get in the terms of the "Great Eight" as a Paradox Game would consider it. The numerical value the rating was assigned is provided here as well:
1. United Kingdom of Great Britain (9975)
2. Empire of Holy Spain (9460)
3. Sweden (5750)
4. Mamluk Caliphate (4566)
5. Republic of the Netherlands (3229)
6. Austria (3066)
7. Roman Empire (3056)
8. Denmark (2797)
