Upon re-examining my data at the request of someone who was looking for first and second place, I realized that I had messed up a couple of things.
First of all, the data I was using before was including adventurers in its numbers, which changes the picture slightly. Second of all, the data were slightly old, and I have updated my numbers with the most recent data available to me. Finally, due to the formatting of my calculations, I managed to miss one other realm that beat Eston for doublets in the realm—Rieleston.
So, for reference, here are the realms with a greater than 1.25 ratio of nobles to players (meaning that at least 1/4 of the realm has 2 characters there):
- Lukon: 1.44*
- Darka: 1.33
- Barony of Makar and Armonía: 1.32
- Rieleston: 1.3
- Outer Tilog: 1.29*
- Eston: 1.28
- Enweil: 1.27
- Obsidian Islands: 1.25
*Due to the nature of the Colonies, with only 1 turn per day, I do consider it to have a different demographic profile than the rest of the continents, and thus I don't consider these numbers to be truly comparable with those from other continents.
So, as you can see, Eston itself isn't quite as bad as I'd originally thought, though it's still not great. Rieleston is noticeably worse, though.
Honestly, the only two things that surprise me about this list are that Armonía is on it, and that CE isn't. They're actually down at a ratio of 1.15—though I do wonder, if I analyzed those 15% of its players who have 2 characters in the realm, how many of them would be old-timers.
