I am flattered that you decided to use the term Radius to describe the alliance between Britain, France, Russia, the Confederacy, et al.
That being said, I understand that there isn't an official map of how Europe looks like after the FGW. Therefore, it is fair game to the artist how they imagine what size countries like Poland, Ukraine, Belarus, Germany, etc. could be.
I think it was about time for the appearance of a third iteration of a TL-191 map thread.
I'll do a link dump of the maps that I've created or modified to this thread soon.
Also, I've thought about this for a while: Despite the TL-191 series being such a niche "franchise", I still think that it has enough influence from fans to catalogue some of the jargon, inside jokes, and fan creations that have been made on this forum. We could make a vote on what ideas could be considered
fanon if they are popular enough.
Phrases such as
PolishEagle's Sauerkraut Westerns;
Alterwright's written alternate history of Confederate soldiers being part of the French Foreign Legion, Pre-Secession Reputation Reports, Snapping Turtles during FGW, Büffel-Soldaten ;
Soundwave3591's Art on Military vehicles and soldiers,
cortz#9's Confederate Hound Dog plane art, and many others who have contributed could be given some sort of inside recognition.
